Recent legislation mandates Amtrak to become pet friendly.
March 6 2015
The White House and Republican-controlled House of Representatives don't agree on much these days, however, in a rare bipartisan vote, a bill was passed this week that will continue funding to Amtrak and make the train line pet friendly. While the White House didn't fully agree with the legislation, it's believed that support on both sides was won over by the pet-related part of the bill. Amtrak will now be mandated to create a pilot program that welcomes dogs and cats system wide.
The provision was included in the bill by California Representative Jeff Denham who has been advocating for pet friendly trains since he realized several years ago that he couldn't ride Amtrak with his French Bulldog, Lily.
The bill specifically directs Amtrak to figure out parameters of the program within one year of its passing, which will need to include a designated pet car on each train. Traveling animals will ride in a kennel and be subject to a to fee (amount to be determined).
For now, pet kennels must fit within Amtrak's carry-on luggage size limits, 28" x 22" x 14". That's bad news for big dogs, but it is larger than the standard in-cabin size for pets traveling by plane.
Hopefully it won't take long for Amtrak to finalize the parameters since they've already been running pet friendly trains in a pilot program on two lines in Illinois since last spring. 145 dogs and cats have ridden the train since the initiative began.
It's always great to see more pet friendly travel options, particularly alternatives to air travel. I hope to see the kennel size increased in the future to make Amtrak accessible to more dogs.

Scientists have possibly found the protein behind osteosarcoma.
March 5 2015
With so many dogs I know affected by cancer, I'm always excited to learn about new breakthroughs in the search for a cure. The latest research out of the University of Wisconsin-Madison School of Veterinary Medicine is an important one, as they may have identified the biological mechanism that gives some cancer cells the ability to form tumors in dogs.
Scientists at the school were interested in why only some cells generate tumors. What they found was a connection between the increased expression of a particular gene in tumor cells and canine bone cancer.
The study looked at cell lines generated from dogs with osteosarcoma, a common bone cancer that also affects people. After removing tumors from the canine participants, the cells were grown in a lab and transplanted into mice. The researchers then looked to see which lines developed tumors and which did not, and the differences between them.
The scientists identified several hundred genes that expressed differently between the tumor-forming and nontumor-forming cell lines. One protein in particular, called frizzled-6, was present at levels eight times higher in cells that formed tumors. Proteins and RNA, like frizzled-6, are responsible for many vital cellular functions, like receiving information and activating pathways that regulate growth. When these pathways go awry, they may contribute to the development of tumors.
Though a preliminary association has been made, it's not clear what role frizzled-6 plays. It's possible that the frizzled-6 expression may be inhibiting a signaling pathway that contributes to the formation of tumor-initiating cells.
Next the researchers want to better understand the findings. Does frizzled-6 serve as a marker of a more aggressive disease? Will identifying the protein improve the accuracy of prognoses? The veterinary school plans to continue the study in order to answer these questions, in addition to expanding the research to human cancer patients. They'd like to confirm that frizzled-6 is truly what gives these cells the ability to form new tumors, or if it's possible that it's part of a combination of multiple genes that lead to tumor formation.
If they can prove that frizzled-6 is behind the tumor-forming cells, the protein may provide oncologists with another target for therapy which would improve outcomes for cancer patients, both canine and human.

Enjoying the snow with our pets can be fun, but dangerous.
February 27 2015
As an avid snowboarder, there's nothing that I would love more than to share my favorite winter hobby with my dogs. I'm captivated by ski patrol canines that help rescue people trapped in avalanches and dogs that run alongside people cruising down in the backcountry. But the sharp edges on skis and snowboards that let us carve into icy slopes also make it potentially dangerous for our four legged companions.
Avid backcountry skiers Don and Polly Triplat regularly take their dogs Scarlet and Brodie with them in the Sierra Nevada mountains. Normally they're careful to separate the dogs from the ski party as each person tears down the mountain, but accidents can happen in a split second.
Earlier this month the couple was skiing with friends, when Scarlet darted in front of a friend just as he was starting his descent. Scarlet managed to get caught in his ski causing a tumble that left the skier unharmed but left the poor pup with a deep gash in her front leg. The wound was so serious that it sliced through her skin, muscle, and artery to the bone, resulting in an injury that could result in fatal blood loss.
Fortunately the Triplats are trained in wilderness first aid and were able to calmly assess the situation and make a plan of action. Don quickly clamped Scarlet's artery to the bone and created a tourniquet with gauze and duct tape to stop the bleeding. Then Don carried Scarlet on his shoulders as he descended the mountain, while friends helped. One skied ahead to break trail, creating an easier path, and another raced ahead to reposition their car to the nearest place they could reach the road.
Since the accident, the Triplats have stopped taking their dogs on backcountry downhill trips and have opted for including them on tamer cross country skiing excursions. They were fortunate to have the training necessary for a successful outcome, but the couple wants to warn other skiers to be aware that taking a dog skiing is a big responsibility.
This story makes me think of the rescue of Missy in Colorado. It shows how important it is to be prepared for an emergency when taking your dog into the backcountry, whether it's skiing, hiking, or boating. Always bring first aid supplies (and know how to use them!) and have a plan for how to carry your dog to safety (when hiking, I always bring a backpack large enough to carry my dog if necessary).
Do you ski or snowboard with your pups?

Organizations specialize in helping people and reversing stigma.
February 24 2015
Pit Bull lovers are constantly battling the breed's negative reputation. It can be heartbreaking to see someone cross the street to avoid your pup or usher their kids away at the park, but it happens every day to bully breeds. Every friendly, well socialized Pit Bull is an advocate for the breed, but it can be slow to shift mainstream perception.
Two organizations are on a mission to change that stigma by recruiting rescue Pit Bulls to help people. The Animal Farm Foundation's Assistance Dog Training Program in New York trains shelter Pit Bulls to push wheelchairs or help people regain their mobility and avoid falls. It's believed to be the only American training school that exclusively trains shelter Pit Bulls to be service dogs.
Another group in Chicago, Pits for Patriots, trains rescued Pit Bulls as comfort, therapy, and support dogs for veterans, police officers, and firefighters. The organization's co-founder, Kelly Yearwood, says that veterans and first responders identify with bully breeds because they've both seen a lot of trauma.
For former Marine, Joe Bonfiglio, his Pit Bull service dog, Zen, has been a life saver. Joe was diagnosed with post-traumatic stress disorder after returning from Afghanistan and struggled to get his life back to normal. Now he can hang out with friends, shop at the mall, and has even started to take classes at a local college.
Not everyone agrees that Pit Bulls should be trained as service dogs, but if the right evaluation and training protocols are in place, it seems like a win-win. Pit Bulls make up the overwhelming majority of my local animal shelter, so this is a great way to give them a loving home and a purpose.

Study shows that dogs can discriminate between our expressions.
February 20 2015
I don't think that we need a study to know our pups can tell when we're happy or sad, but it's still fun to see formal research explore our dogs' abilities and inner thinking. With all of the canine cognition labs cropping up at colleges around the world, there's been a lot of research showing that dogs can read human emotions. However a new study coming out of the University of Veterinary Medicine Vienna claims to represent the first solid evidence that an animal other than humans can discriminate between emotional expressions in another species.
In this study, the researchers set up an experiment that they believed could only be solved by applying knowledge of human emotional expressions to unfamiliar pictures. The dogs were trained to discriminate between images of the same person making either a happy or angry face. In each case, the canine participants were only shown the upper or lower half of the face. After training on 15 picture pairs, the dogs' abilities were tested in four situations where they were shown (1) new faces (but the same half as in the training), (2) the other half of the faces used in training, (3) the other half of the new faces, and (4) the left half of the faces used in the training.
They found that the dogs were able to select the correct facial expression more often than would be expected by random chance in every case. Not only could the dogs learn to identify facial expressions, but they were able to transfer their learnings to people they'd never seen before.
Interestingly the researchers also discovered that it was harder to get the dogs to associate a reward with an angry face, suggesting that prior experience had taught them to stay away from a person that looks mad. From my own experience, dogs learn this very quickly!
Next, the scientists hope to study how dogs express emotions and how those emotions are influenced by people.

Iowa pup treks to Mercy Medical Center in search of her mom.
February 16 2015
Nancy Franck had been in recovery post-surgery at Mercy Medical Center when she got the surprise of her hospital stay. When Nancy left home in Cedar Rapid, Iowa, she had to leave behind her beloved Schnauzers, Sissy and Barney. About two weeks into her hospital stay, Nancy's husband, Dale, noticed that Sissy was missing. He frantically searched for the 11 year old dog everywhere, but couldn't find her. About four hours later he got a call from hospital security with Sissy.
A surveillance camera in the hospital lobby caught the determined pup entering through automatic doors and wandering around. Sissy ended up being successful in her mission to see Nancy. When Dale's daughter came to pick her up, the hospital allowed Sissy to have a surprise visit.
Although the Francks only live 20 blocks from Mercy Medical Center, but the've never walked there before with Sissy. However, Nancy and Sissy have always had a special bond, with Sissy “choosing” Nancy when they firtst met eleven years ago. The then eight week old puppy came right up to Nancy, pawed at her leg, and then fell asleep on her shoulder.
Over a decade later, I can't think of a better way to be cheered up at the hospital!

Is a canine version of the popular cat cafe on the way?
February 12 2015
There's been a lot of talk recently about cat cafes popping up in cities like New York and San Francisco. The feline establishments have long been in a fixture in Tokyo, giving tiny apartment dwellers their pet fix. While Japan now has cafes that feature all sorts of animals from owls to goats, the concept is just starting to trickle over to America. I'm guessing we'll never see a goat cafe in the States, but a canine version may be on the way.
Two recent Indiegogo fundraising campaigns have been trying to raise money to open dog cafes that will showcase adoptable pups in New York and Los Angeles. These cafes aim to reinvent the way we connect with homeless pets. Besides coming up with the funding, the main challenge is working within health codes. To work within the rules, both ventures plan to create two adjacent, but separate businesses where you could order food in one location and take the treats to enjoy in the space with the dogs.
Living in New York City, I have a lot of friends who love dogs, but can't have one because of their apartment rules or long work hours. A dog cafe would be a great way for people to get their pet fix and meet fellow animal lovers. Meanwhile the dogs can meet potential adopters and get socialized.
The Los Angeles Indiegogo project didn't meet their financing goal in time, but the New York one is still soliciting donations through February 21. However, if the dog cafes don't pan out, there are still other ways to satisfy your pet fix, like volunteering at your local animal shelter.

Researchers study wolves to prove the origin of the human-dog relationship.
February 8 2015
Many studies have show that dogs can understand human gestures, while chimpanzees cannot. This initially came as a surprise to scientists because of our genetic ties to primates. It was thought that canines developed this ability through domestication, however a series of new studies suggest that this capability may be more innate.
Behavioral scientists from Austria's Messerli Research Institute and the Wolf Science Center hypothesize that the dynamic between wolves and their pack mates could've provided the basis for today's human-dog relationship. Because of this, they believe that selection for social attentiveness and tolerance was not necessary during canine domestication.
To test their hypothesis the researchers have been working on a series of experiments to examine social attentiveness and tolerance of wolves and dogs within their packs and toward humans. To compare what could be attributed to evolutionary changes rather than individual experiences, the researchers compared dogs and wolves that had been raised in an identical way and socialized with humans to a similar extent.
The first study tested the ability of the dogs and wolves to pay attention to human actions. In the experiment, the subjects observed a familiar human either hide a food reward or pretend to hide one. There was also a control round where the food was hidden before they entered the test area (and would have to detect by smell). Both the dogs and wolves were equally good at differentiating whether or not the person actually hid food or not. Interestingly dogs outperformed the wolves in both test and control conditions, suggesting that they relied on their nose more than the wolves to find the hidden food.
Another experiment looked at the wolves' ability to follow gaze. The researchers set up scenarios to see if wolves would follow the eyes of people and pack members, both looking into distant space and around barriers. They found that the subjects followed human gaze just as readily as their fellow wolves, implying high social attention and willingness to accept people as social partners who might provide important information.
So far the researchers' work has shown that wolves pay as much attention to people as dogs do, supporting the hypothesis that the human-canine bond was not necessarily selected for through domestication. The behavioral scientists plan on continuing their experiments to further their theory. It's certainly interesting to see that the understanding we have with our dogs could be in their DNA!

Dogs die after drinking water from California's Lake Chabot.
February 3 2015
When I hike with my dogs, I always bring enough water for them to drink, but they often end up taking a few sips from streams along the way. Generally I don't think too much about where the pups are quenching their thirst (aside from keeping them out of very murky puddles), however a recent report of dogs dying from toxic algae is making me much more aware of trail side water.
In the last two months, three dogs have died after drinking water from Northern California's Lake Chabot, located in a popular park. The lake has had a dangerous algae bloom since September, which is harmful to humans and animals. These blooms normally happen in late summer, but unseasonably warm temperatures and drought conditions have caused algae to proliferate well into the winter months.
Park and municipal officials have urged an urgent warning for people to keep dogs away from the water, and have posted additional signs along the lake trails.
I have a portable water filter that I use for longer backpacking trips, but it's important to know that these devices will not make algae bloom affected water safe to drink. Use your judgement and keep an eye out for water sources your dog may try to drink from.
If you're planning on hiking in a park, check the area's web site before you leave to be aware of any warnings. Algae blooms are often foamy, scummy, or slimy looking with an offensive odor. They can be a variety of colors, such as blue-green, brownish red, pea green, or white. Not all blooms are toxic, but you can't tell just by looking at it (a toxin test is required). Generally it's best to direct your dog to clear, flowing water sources.
What precautions do you take for thirsty pups on the go?

Researchers look at how our personality affects pet care.
January 29 2015
There's a lot of joking today about “helicopter parents” who are too overbearing with their kids. It may not be the best way to raise children, but what about pets? Two researchers at UC Berkeley and California State University are collaborating on a study that will look at personality and attachment style, how we relate to others, and whether it can predict better pet care.
In the first part of their research, Mikel Delgado and Gretchen Reevy surveyed more than 1,000 pet lovers across the country. They found that those who expressed the greatest affection for their pets were also rated among the most conscientious and neurotic. While these may be bad characteristics for human parents, it may work better for pets, who will never be independent. Cat lovers tended to score high on anxious attachment, meaning they tend to need more reassurance from their pets. Both dog and cat lovers scored low on avoidant attachment, suggesting that they enjoy close relationships with their pets.
This was the first study to combine principles of human attachment theory to pet people's personality types. Next Mikel and Gretchen plan to do further the research by investigating whether greater affection and anxious attachment is associated with better care and understanding of their pet's needs.
If you're interested in learning more about your attachment style (based on human relationships), take this long or short online test.
