News and insights from special guests—from experts to enthusiasts.
The discovery of one of the last pure landrace dog breeds, the Sardinian Sheepdog (Cane Fonnese, Fonne's Dog) was celebrated by scientists in the October 11, 2016 issue of the journal Genetics.
The study revealed that the large flock guardian dog travelled the same ancient migration routes as the Sardinian people. And like their people the dog's genetic signature remains distinctly isolated.
A landrace is a regional type of domestic animal that over a long period of time has adapted to its purpose and environment through unregulated selection for behavior. Landrace dogs were common up through the early 1800s, but most disappeared as a consequence of cross breeding with dogs introduced by travelers.
The Sardinian Sheepdog is a breed because it's been created within an isolated population of animals. Sardinian shepherds allowed only their best working dogs to reproduce.
What's appealing to scientists is that the dog remains uncontaminated by modern artificial breeding practices, resulting in a robust genome. Sardinian dogs don't all look the same, but all have in common a high drive to guard sheep.
Sardinia is the second largest island in the Mediterranean Sea, just south of Corsica. The island was populated in multiple waves of people as far back as the upper paleolithic.
The study also revealed that the Sardinain Sheepdog originated from sight hounds developed in the near and middle east as well as large mastiff-like sheep guarding dogs from an area around Hungary.
Their genomic map mirrors human migration. Just like their dogs, the people of Sardinia derive from Hungary and the middle east.
Science Daily offers a reader-friendly description of the significance of the study: "Just as Sardinian people have long provided a wealth of genetic insights to scientists, the canine natives are an example of an isolated population that could prove a powerful resource for finding genes that influence health and behavior."
There are few more joyfully optimistic moments in life than the day you bring a new dog into your home. Your new bundle of fluff will add a new dimension to the household, helping you to see your home in new ways, providing unexpected moments of love and humour, and bringing demonstrable benefits to your mental health. But that element of surprise a pup brings can turn into stress when your new best friend discovers ways to damage your stuff – or herself – that you had never imagined in the days of anticipation before picking up her up.
The right preparation is crucial when introducing a new dog into your family, and even if you’ve had dogs before, chances are it’s been a decade or more since you went through that difficult teething period – so a little refresher is called for. Every dog has it’s own needs, and you’ll want to check with the breeder or rescue home as to your new pal’s particular dietary and exercise needs – and any emotional quirks of which you need to be aware. Shop for the toys, tools and barriers you’ll need in advance, and set out a plan as to which areas of the house she will be allowed in, and where on your property she will sleep, play, go to toilet and so on. Ensure everyone in the family knows the rules, and their own responsibilities.
Once she arrives, it can be tempting to just play with and dote on her until you both collapse exhausted on the sofa – but establishing some ground rules straight off is essential. Take her to her toilet place, and remain with her until she’s done: do this regularly until she knows where’s where. If you already have a dog, introduce the new siblings on neutral ground. To your first dog, this suspicious character will be an intruder on their territory, so getting them to bond is a sensitive business.
There’s a lot to consider in preparation for bringing a new dog home, but thankfully this new infographic breaks it down into a handy checklist. Be sure to go through it in detail before pooch arrives, and you’ll be set for a beautiful – and fun-filled – life together.

I am crazy about the pet stroller!
As far as I’m concerned, it is the greatest invention. I originally bought one to take my senior dog Red on outings, but sadly I now have another use for my stroller. Jack, my young dog (around 4 years) recently underwent spinal surgery. He is unable to walk yet and facing a long recovery, so I take him out twice a day to relieve boredom.
If you need a stroller in your life but your dog refuses to have anything to do with it, don’t worry, because this training will help.
If your dog is unsure or even downright terrified, please do not pick him up and plop him in. That can make him more fearful, and turn this into a bigger deal than it ever needed to be.
Step 1: Set the stroller up somewhere in your house, then leave it there for your dog to investigate.
Step 2: If he’s calm, give him a treat, or play with a favorite toy near the stroller.
Step 3: If he’s nervous, back up until he’s at a distance he’s comfortable with, then play with him or give him a treat. Make sure he can see the stroller.
Step 4: Gradually move closer and give him a treat or play with him.
Step 5: Once he’s fine next to it, pick him up, put him in and give him a treat. If at any point he panics, stop and resume the training later, from the last point where he was still comfortable.
Step 6: Start rolling. My dogs get very irritable if I put them in the stroller, and we don’t start moving within seconds. If that’s happening with your dog, he may just want to get going already.
Step 7: Roll him out into the garden. If he’s uncomfortable or nervous being outside, repeat the first few steps, only this time outside. You may be able to breeze through once he gets used to the change in environment.
Step 8: Time to hit the streets! Start off close to home then venture further afield. Try a quiet street, the park, then a busier area, public transport perhaps.
Why so many steps?
Some dogs will love the stroller right away, but for those that need time, taking training slowly greatly increases the likelihood of success. Offering treats and favorite toys creates positive associations. You want him to see how many great things happen when he’s in the stroller.
Keeping him safe
Put a harness on your dog, and attach a leash that you hold, to prevent him jumping out in a stressful or uncomfortable situation. If I’m in the middle of a crowd, and my dog(s) seem a bit nervous, I zip the awning to enclose the stroller, creating a den they can relax in.
Pet stroller training: conclusion
Your dog may hop right in and wonder why he’s not moving, or take a bit of convincing. For dogs that need time to adjust, this pet stroller training will get you teaching your dog to ride in a stroller in no time.
Have you ever noticed your dog taking interest in something you are watching on the television? If so, you may have wondered what they might be thinking, or if they are even seeing the same things that we are, or in the same way that we are.
As it turns out, dogs do in fact notice and understand pictures that they see on the television screen, as well as the sounds that accompany them. These days, with the evolution of television and more high-resolution and digital broadcasting, dogs literally see a brand new picture, with much more clarity than before. There are even scientific studies in which the results show us how they see and process images, why they are attracted in the first place, and whether or not they understand what they are watching.
Is There Any Proof?
A 2013 study shows that dogs can pick out pictures of other dogs apart from humans, and group them into categories using only visual clues. It is a known fact that like-species gather for social interactions and dogs recognized and were drawn to their own species on the television screen more readily than images of anything else. Possibly an evolutionary measure based on breeding needs, it is an important facet of a dog’s life.
There is even a channel especially for dogs on HDTV called DogTV. The channel has more frames per second than regular television and is specifically colored for a dog’s specific sight. Since dogs can process visual information faster than humans, what they see is quite different from what we see.
Herding dogs, in particular, are motivated by moving objects (think flocks of sheep). They watch the television much more intently that other breeds for this reason.
Human depth perception is the ability to distinguish a 3-dimensional worldview from the 2-dimensional images from the retina. This comes about from the human cognitive ability to reason and formulate similarities of experiences. For dogs, the term could more readily be described as depth sensation as their means of locating objects that they have seen.
The evolutionary adaptation known as binocular vision allows the eyes of some mammals to move in simultaneous directions, also known as "vergence". When something is view close up, ocular convergence is promoted. Seeing objects in the distance, on the other hand, promotes ocular divergence. Both canine eyes then work together in a state known as fixation where two different images come together to create depth sensation, which is promoted by binocular overlap.
This comes into play while dogs watch television in that they realize the objects are not actually with them, but on some other plane all together. It doesn’t thwart their curiosity, however, and often leads to complete fixation on the images on the television screen.
Field of View
The term "field of view" describes how different parts are seen at any given point in time along the visual plane. Dogs who are predators have a very narrow field of view and depend more on binocular overlap to, or depth sensation, to visually locate and isolate prey. Their maximum field of view is about 240 degrees, while animals of prey have a nearly 360-degree field of view, for protection reasons.
This field of view possessed by dogs may immediately attract some breeds to a moving picture, but once they determine that there’s nothing really happening, they may quickly lose interest.
Humans have many more cones in their eyes than dogs do, therefore human eyesight is very sensitive to movement of bright lights. A dog’s retina’s, which have far fewer cones, are much more sensitive to lower light situations. They are also much more capable of noticing a moving target and can hone in on moving objects at further distances than stationary objects that are quite near them.
This ability to monitor movement is another reason dogs are capable of seeing and paying attention to television. They may not have a good idea of what is going on within the program, but they can see that action is taking place. When their curiosity is satisfactorily peaked, they will pay more attention.
Dogs and Television
Old style American televisions that work from tube technology have a frame rate of 60Hz, meaning that the frame refreshes sixty times per second. Newer television, models known as HDTV, refresh at a much faster rate. Many images on the television screen appear stationary to humans, as their rate of vision is slower than that of the television. At about 50Hz, images would appear, to the human, to look like images from a flipbook. Dogs, on the other hand, get the flipbook imaging up to 75Hz, so the images have to have a higher refresh rate to appear fluid to a dog.
To dogs, the older televisions reflect images that they perceive as simple flickers of movement or light, however, the newer televisions present more fluidity and make images appear more realistic to the canine eye’s abilities.
Some dogs even use face-tracking as a means of identifying and relating to information they see on the television screen. However, as a study has shown, face-recognition in dog’s is a trained behavior that can cause dogs to focus on the images that they see on the television screen, effectively overshadowing their natural abilities and responses in this scenario.
Dogs are initially attracted to the television because of certain sounds that they hear. Once the noise has their attention, and they then find out where the sound is coming from, they begin to focus on the images and, depending on the breed of dog and the way their eyes function, interact with the stimulus or not. It was found that some of the sounds that elicited the most response from dogs was other dogs barking or whining, the sound of the human voice giving friendly commands or praise and the sounds of squeaky toys.
Transporting shelter animals to northern California, Oregon and Washington
Since its inaugural journey on Valentine’s Day of 2015, Rescue Express has been the ticket to a guaranteed future for more than 5500 animals who were once at risk of euthanasia. Headquartered in Eugene, Oregon, Rescue Express picks up dogs and cats from shelters located mostly in high-volume shelters in Southern and Central California and delivers them to underpopulated shelters in the Pacific Northwest. Twice monthly, the former school busses — now outfitted to provide and comfortable animal transport — have been traveling a well-worn route along Interstate 5.
Then, tragedy struck the Gulf Coast. So in early September, the organization expanded its outreach to include animal victims of the recent flooding in Louisiana. With local shelters unable to accommodate the influx of displaced pets, several national and local organizations worked in concert to help bring dogs and cats — those for whom owners could not be located — to safety around the U.S. The Rescue Express bus picked up 55 of those pups who had been transported to Salt Lake City. From there, they headed farther west to “receiver shelters” in Oregon and Washington where they can be adopted into loving homes.
For now, transport needs are still great along the I-5 corridor. But plans for the group’s future include initiatives like providing low-cost spay/neuter services and working with local lawmakers to improve animal welfare regulations. Want to help?

Celebrate your furry family member in a contemporary or modern setting with these 8 decorating ideas
You’ve added his daily walks to your routine, and you can always, always take time out for a belly rub. But incorporating your dog into your contemporary or modern decor might be the one of the biggest challenges of pet ownership (besides getting him to stop eating the cat food).
Here are eight ways to celebrate your canine in style.
1. Think small. Small spaces like this bathroom are great places to experiment with quirky wallpaper. Just don’t add too many competing pieces; this Osbourne & Little paper works because the room follows its simple black and white motif, punctuated only occasionally with pops of yellow.
2. See things through a child’s eyes. The family dog is one playmate your child will never tire of. Let your little one celebrate his or her buddy with a mix of dog-themed artwork and pillows. Silhouettes keep things looking clean (even when the bed is unmade), while illustrations add whimsy.
3. Focus on Fido. Your dog is a central figure in your life. So why not make him the focal point of one of your most-used rooms? Artist Bill Sullivan created this painting for a family of loft-living New Yorkers. Industrial accents, a limited use of color and leaving the portrait unframed keep the room casual and understated.
4. Consider placement. This pack of rustic wood dog sculptures could easily seem out of place in such a clean, modern home. But placing the pack so that it’s emerging from a makeshift den gives these sculptures context.
5. Mix and match. Eclectic rooms are great places to let your decor speak to who you are — particularly if you’re a dog lover.
6. Go vintage. Humankind has celebrated its best friend for centuries, so spend some quality time at your local flea market and source a vintage find, like this gorgeous black statue of a greyhound in recline.
7. Have an outside dog. After you take enough morning walks and trips to the coffee shop with your best friend in tow, it’s funny how people begin to use your dog as a reference point for getting to know you. A canine-themed art piece like this one by Dale Rogers is a great way to mark that this is where Buster lives … and so do you.
8. Embrace the unexpected. Like the time your pup scaled a 6-foot wall in a single leap, an unexpected detail with a canine twist — like this pair of balloon dogs — is a great way to mix things up. To make your statement piece blend in a little more, choose something that fits the room’s general color palette and feel.
9/11 SAR Dogs honored with commemorative statue
The service dogs that responded to the World Trade Center and the Pentagon in the wake of the September 11, 2001 attacks have not been forgotten. However, monuments to their service are few compared to those devoted to two legged responders. On Wednesday August 17, New Jersey officials gathered at the Essex County Eagle Rock September 11th Memorial in West Orange to do their part to change that. They dedicated a new commemorative statue honoring the Search and Rescue Dogs of 9/11.
The four-foot tall bronze dog sits atop a 12-inch slab of granite, and weighs nearly 5,000 pounds. It was designed by Oregon artist, Jay Warren and paid for by corporate donations. The West Orange 9/11 Memorial opened in 2002, almost exactly one year after the attacks. The park overlooks Manhattan across the water. Citizens once gathered there, helplessly witnessing the chaos at Ground Zero.
In September 2001, countless heroes emerged from obscurity to aid their country in its time of need. Men and women of law enforcement and fire rescue courageously faced the devastation alongside everyday citizens. The new West Orange monument stands as a reminder that not all 9/11 heroes were human.
Roughly 350 Search and Rescue Dogs worked tirelessly in the tragic aftermath searching for survivors; and after, searching for human remains. Sifting through the jagged rubble and blinded by smoke and debris, the dogs battled exhaustion and emotional distress.
After hours of searching and finding no one alive, some handlers would ask for a volunteer to hide amidst the rubble to be “located”, helping to raise the dogs’ spirits. Even when the search mission became one of recovery instead of rescue, the dogs carried on diligently, providing what little peace they could for the families of the victims.
In a press release for the commemoration of the new statue, Newark Public Safety Director, Anthony Ambrose said:
"Search dogs covered 16 acres of land at Ground Zero covered with metal and debris, and went where humans could not go. This is a fitting way to remember how many families gained some sort of closure because of the work by dogs."
The presence of the dogs at the recovery sites had an even greater impact than many may realize. Dutch photographer, Charlotte Dumas is the author of the 2011 book, Retrieved featuring the stories and portraits of 9/11 canines. She interviewed Denise Corliss, handler of famous 9/11 FEMA Search Dog, Bretagne. Dumas recounted an emotional narrative from her time with Corliss to Daily Mail UK:
Most Search and Rescue Dogs are trained by non-government organizations. Often their handlers are civilians as well. Many of the teams that responded to Ground Zero did so on a volunteer basis, simply because their country needed them. Now these pups are getting the recognition they deserve from the folks in Essex County, NJ.
Researchers Richard G. Lea and associates published on Aug 9th, 2016, a report entitled Environmental chemicals impact dog semen quality in vitro and may be associated with a temporal decline in sperm motility and increased cryptorchidism. (In Nature, Scientific Reports 6, Article number: 31281 (2016) doi:10.1038/srep31281). Against the background of declining semen quality and rising incidence of undescended testes (Cryptorchidism) in humans associated with exposure to environmental chemicals (ECs) during development they report that “a population of breeding dogs exhibit a 26 year (1988–2014) decline in sperm quality and a concurrent increased incidence of cryptorchidism in male offspring (1995–2014). A decline in the number of males born relative to the number of females was also observed. ECs, including diethylhexyl phthalate (DEHP) and polychlorinated bisphenol 153 (PCB153), were detected in adult dog testes and commercial dog foods at concentrations reported to perturb reproductive function in other species”.
Estrogen-mimicking, endocrine-disrupting chemicals have become virtually ubiquitous in many of the foods we consume, some of which, along with their byproducts, are included in most manufactured pet foods; in the can-linings of moist, and in plastic bagging and wrapping of dry and semi-moist foods. Plastic may also be processed into the manufactured food along with discarded meats, packaging and all.
Food wrappers and other industrial and commercial products from firefighting foam to water-repellant clothing contain poly-and perfluoroalkyl substances, or PFAS, detected in drinking water and having endocrine disrupting and carcinogenic properties.
Dioxins, predominantly released as byproducts of human activities such as incineration and fuel combustion, are a most potent class of carcinogens and endocrine disruptors. They are ubiquitous in the environment, and from the soil and vegetation undergo bioaccumulation in the fat (tallow) of cattle, and sea foods, especially farmed salmon, which are common pet food ingredients. Their adverse impact on wildlife reproduction and sexual development in several aquatic and terrestrial species has been well documented.
Other estrogen-mimicking and endocrine disrupting contaminants of pet (and human) foods include glyphosate and other herbicide residues in corn and other cereals along with phytoestrogens in soy products especially in GMO soy, a widely used pet food ingredient.
Aflatoxin B1—yet another endocrine disruptor-from the mold on corn and other cereals, is often found in dry dog foods which are recalled too late to save many dogs from acute toxicity and death. Aflatoxins, dioxins and other endocrine disruptors, estrogen mimics, carcinogens and obesogens have harmful consequences in extremely low concentrations in the diet over an extended time period with possible synergism operating where one contaminant increases the toxicity of one or more others; and prenatal, epigenetic, developmental effects on the offspring of exposed parents.

Statement to appear in Animal Doctor syndicated newspaper column by Dr. Michael W. Fox.
It can be dangerous when pets’ body temperatures get just a few degrees above normal. Elevated temperatures can lead to heat stroke, dehydration and hyperthermia. Fortunately, with a little planning and preparation, keeping four-legged friends safe in hot weather can be a breeze. Here are six easy ways pet parents can help their pets beat the heat.
• Chill out with a tasty treat. Freeze low-sodium chicken broth in a popsicle mold or ice cube tray for dogs and cats to enjoy on a hot day. See our recipe for Frozen Sunrise treats. Try Karen B. London’s Frozen Kong stuffing tips.
• Hose down hot pavement, patios and porches before letting your pets outside. A little water could go a long way toward keeping paws cool and avoiding paw pad burns. Pet parents can also run cool water over their dog’s feet.
• Say yes to ice water. Adding ice to pets’ water bowls creates a game for curious canines—they’ll bob for ice cubes and stay cool and hydrated in the process! Be careful for choking and teeth damage with ice, as always assess your individual dog’s abilities.
• Cool the crate. If your pet will be crated while you’re away, try freezing two-liter water bottles and placing them on top of the crate. They’ll give off cool air and help keep the spot cool.
• Wear a cold compress. A refrigerated wet bandana will help keep Fido cool and stylish this summer—this is especially effective because of the temperature receptors around dogs’ necks.
• Make a splash. A backyard baby pool is a great way for pets to stay cool (and it’s fun too!).
Toxic chemicals also found in dog food
A long-term study conducted in Britain has found that male dogs are losing fertility, and that exposure to environmental chemicals (ECs) that have leached into the environment may be to blame.
The dogs—Labradors, Border Collies, German Shepherds and Golden Retrievers bred to aid the disabled—made an ideal group to explore the larger question of a decline in human semen quality that has been occurring since long before this study.
This twenty-six year long study, 1998-2014, was conducted by Richard Lea and colleagues at Nottingham University’s school of veterinary medicine. They collected annual samples of semen from dozens of dogs, all from the same breeding program, all healthy and well cared for. Each year, the same problem recurred; a 2.4 percent dip in sperm motility, that is the ability to swim in a straight line. In addition to monitoring semen quality, they analyzed health records, finding an increase in cryptorchidism, a condition in which the testicles fail to extend normally to the scrotum. Over the same years, fewer male pups were born than females, also there was an increase in fetal and prenatal female mortality.
And, lurking in the samples of semen and testicles of dogs obtained from neutering, it found ECs—chemicals that tamper with hormones. The chemicals include polychlorinated bisphenol (PCB), a compound banned in 1977, and diethylhexyl phthalate (DEHP). PCBs don’t readily break down while phthalates are common in a wide number of products, from cosmetics to detergent. Both chemicals are associated with fertility issues and birth defects.
In human babies, exposure to chemicals has been linked to faulty development of semen quality and cryptorchidism. According to the study, such reproductive problems often cluster in geographical areas, and so are suspected of having a common cause; exposure to hormone-disrupting chemicals is “thought to be the initiator.” To explore the same possibility in dogs, chemicals were measured in canine testes and semen taken from the same geographical area where the study took place.
Both chemicals “perturbed sperm viability, motility and DNA integrity in vitro.” The researchers concluded that the direct effects of chemicals on sperm “may contribute to the decline in canine semen quality” that parallels that in humans.
The same ECs were found in a range of commercially available dog foods. DEHP and PCB153, “were detected in adult dog testes and commercial dog foods at concentrations reported to perturb reproductive function in other species.”
While the brands were not named, they are reported to be both wet and dry forms sold worldwide. The scientists don’t know how the chemicals made it into the food, but since they are not deliberate additives, they may have leached from the packaging or processing sources.
These overall findings are troubling, but they also noted that: “Amongst the dry dog food samples, one sample designed for puppies (1 to 24 months of age) had higher concentrations … relative to the other samples tested.”
Plus, while the researchers cannot say the dog food is a direct source of the ECs, the New York Times reports that "Dr. Lea said it was probably a major one."
What is known is that the chemicals wound up in dog’s testicles, where they messed with sperm motility and viability. “This may be a way by which environmental chemicals directly affect male fertility.”
While the dogs in the study were still able to reproduce, it’s hardly reassuring that, once more, the dogs who share our homes also share our diseases, unwittingly, acting as the “canary in the mine” for us.
