A haircut can change a dog’s behavior, but the reason is not just its new look

A dog that returns from the groomer suddenly becomes playful, walks around proudly and seeks attention. That change may reflect physical comfort, positive attention or, in some cases, stress rather than confidence.

Dr. Catherine Dench, chief scientific adviser at Paw Origins and a veterinarian trained at the University of Cambridge, said removing excess fur, tangled knots, dirt and debris can reduce skin discomfort and make movement easier. Overgrown nails can also affect how a dog stands and walks. Trimming them may improve posture and help the animal feel more comfortable.

“A dog that previously moved cautiously because of discomfort may suddenly seem much more relaxed and confident,” Dench explained. Dogs can also react to their owners’ behavior. After grooming, owners often praise, pet and admire their pets more than usual. Because dogs read body language and mood, they may respond by holding their heads higher, wagging their tails, approaching people or showing more interest in play.

The grooming process itself can be pleasant for dogs accustomed to brushing, handling and the removal of loose fur. A familiar groomer and a predictable routine may help them relax. Dogs with thick or long coats may move more freely once the weight and pulling of the fur have gone.

But not every dog enjoys the experience. Unfamiliar handling, dryer noise or strangers can cause stress. “If a dog hides, trembles, pants rapidly, avoids touch or seems unusually withdrawn after returning home, those are signs of stress, not confidence,” Dench warned.
