Why is my dog always yawning? Is he tired?
Most of the time when presented with a dog who is yawning people say that the behavior is prompted by feeling tired. But, this is not always true! A dog who is curling up and ready for bed might be yawning because they are tired. In most other situations, however, there are different causes for their yawning.
Verified in multiple studies, the main cause for yawning in dogs is as a response to stress. If you pay attention to when your dog yawns, there is likely a pattern. For example, if your dog yawns every time you grab their harness, that indicates that your dog doesn’t like having their harness grabbed.
It has also been hypothesized that dog’s do contagious yawning like people do with each other. However, the results of multiple studies have been overall inconclusive. On a population level it has not been proven that dogs exhibit contagious yawning, but there have been some individual dogs who do. It has also been shown that there is an element of social-emotional, empathy based, and emotional connection factors that will contribute to whether or not the dogs yawn in response to the person’s yawn.
The Bottom Line:
- Dogs yawn for many reasons. They might be tired if it happens when they have just woken up, but most of the time they are self-regulating because they are feeling stressed, anxious, or scared.
