One of the most rewarding moments of owning a dog is returning from a long day only to be greeted by an enthusiastic wagging tail. That gleeful expression signals not only joy but also the intensity of your absence. Studies consistently show that dogs experience stress when their human companions leave. Because a dog cannot grasp the context of a brief departure, a simple exit can feel like an abrupt disappearance. Fortunately, recent research suggests that a brief petting session before you leave can help ease that transition.
In a 2018 study published in the Journal of Veterinary Behavior, researchers compared the heart rates of dogs left alone versus dogs that were petted before the owners stepped out. The findings demonstrated that a gentle touch can significantly reduce physiological stress.
A team from the Universities of Pisa and Perugia examined 10 dogs of various breeds and ages, all without prior separation anxiety or chronic medical issues. Each dog underwent two trials. In the first, owners walked the dog into a fenced yard, then spent a minute talking to a researcher while ignoring the dog. In the second trial, owners repeated the same procedure but petted the dog throughout the minute. After the conversation, owners left the yard for three minutes before returning.
During the three‑minute absence, researchers noted that dogs in both trials spent roughly half their time searching for their owners. However, dogs that had been petted prior to the departure searched more calmly and displayed relaxed behaviors such as lying down. Their heart rates after separation were also lower.
These results challenge the long‑standing “tough‑love” approach that suggests ignoring anxious dogs will help them cope. Instead, gentle attention—whether it’s petting, playing, or simply sharing space—consistently reduces stress in dogs. Earlier research from 1998 in Applied Animal Behavior Science found that petting lowered cortisol, the stress hormone, and helped soothe dogs in stressful environments like vet clinics and shelters.
Petting also works in reverse: it benefits owners. A 2015 study in Anthrozoos showed a strong correlation between cortisol levels in dogs and their owners, and found that owners who kissed their dogs more often had higher levels of oxytocin, the hormone that promotes calm and bonding. The mutual empathy in a human‑pet relationship means that by showing affection, you reinforce the sense of security that both you and your dog share.
In short, a quick petting session before you leave not only eases your dog’s anxiety but also strengthens the bond that keeps both of you healthy and happy.
