Handler Stress Improves Dog Performance
Detection dogs find explosives faster
Scent detection dogs and their handlers work as a team and the behavior of both of them influences the outcome. It has long been known that dogs take cues from their human handlers and may mistakenly identify a target scent (a false positive) based on the person’s behavior. They may also search in patterns based on instructions from the handler rather than according to their own inclinations. A...

Greeting Old Friends
Sometimes dogs are extra excited
When my family visited relatives and friends in Portland, Ore. recently, everyone was glad to see us. However, nobody expressed their exuberance more than Nick and Margaret’s dogs Zuma, Keeper and Radar. These dogs have always liked us and been happy to see us. During this visit, though, they really outdid themselves with their wags, wiggles, spins and general enthusiasm. It’s certainly possible...

Problem Solving Recalls
A dog struggles to figure it out
One day, Marley showed us a limitation in his problem solving ability when he failed to come when called. He just looked at me, cocked his head and stayed exactly where he was. That’s not like him, because he has a good recall. This was definitely not a matter of him being distracted or refusing by choosing to do something else rather than responding to my cue. His recall may not be proofed in...

Dog Fire Hydrant
It adds to the town’s beauty
Dogs and art both dress up a city, and when they are combined, the charm is more than doubled. That’s why I was so pleased when I spotted this fire hydrant painted to look like a dog with a firefighter’s hat in West Jefferson, North Carolina. I already liked the area, and this discovery added to my warm feelings about it. It’s not everyone’s style, to be sure, but I like the whimsical look. I...

Learning to Handle Stairs
Many puppies need a little help
Try crawling down a flight of stairs on all fours, and the experience may give you instant insight into why so many dogs hesitate about going down. Having your head aimed down at such a steep angle takes some getting used to. There are dogs who struggle to go up and down the stairs, but it is far more common for dogs who lack experience with them to be especially resistant to going down. Luckily...

Defusing Awkward Situations
Casual comments when aggression is brewing
The dog was scaring me. He was heading towards us, calling to mind a true wild predator. Moving slowly, silently and with unsettling stillness, this dog was stalking us and I felt true fear. This was a 70-pound tall and leggy dog who had a coyote-like look to him. He was only about 30-feet away at the hole next to us on the disk golf course where we had come with Marley. His family showed no...

Knowing Human Names
It often happens naturally, but can be taught
Many dogs know the names of the humans sharing their home. It’s only natural that they notice that certain words go with certain people. Many dogs will react to the names of their guardians with great enthusiasm when they are not present, perhaps anticipating their return. In the natural course of things, we humans use each other’s names a lot, saying hello, getting each other’s attention, and...

Stick Close!
This means “heel” but I use it for kids
Whatever skills you have from your career or any other experiences in life may get used in surprising ways once you have kids. For me, as a dog trainer and behaviorist, there are many obvious parallels between the way I treat my dogs and the way I behave with my children. To use just one example, I like to keep both kids and dogs in physical contact and right near me when there is any danger from...

Repetitive Behavior in Dogs
A study with insights into welfare
If you think that having dogs who bounce off the walls is problematic for them and for you, you are not alone. “Wall bouncing” is one of the repetitive behaviors that have long been considered indicative of poor welfare and chronic stress in the animals performing them. Other repetitive behaviors that are commonly seen in dogs are pacing, circling and spinning, all of which are generally regarded...

Accidents With Dog Toys
Sometimes toys aren’t fun
I woke up in the middle of the night with every intention of quietly having a drink of water. Unfortunately, I landed on a particularly loud squeaky toy and managed to disturb everyone’s sleep. A few days before that, I got out of bed and stepped on a dog toy that is not designed for the underside of delicate human feet. I woke everybody up that time, too, and not because the toy was noisy. No,...
