Loss of appetite and weight loss

Just like people, stressed dogs can experience loss of appetite and it can lead to weight loss in the long run. It can be dangerous for animals that are already skinny, young, or suffer from any other diseases. 

“This is dangerous for all dogs, but even more so for those that started out medically compromised. For example, dogs that are underweight, young, experiencing other medical problems, or eating a poorly balanced diet,” Brinker said.

Moreover, in some cases, dogs may begin to chew or eat various objects that shouldn’t be swallowed and that may be harmful to their health. So try to pay attention to their behavior throughout the day and call your vet if you notice some changes. “This can include obsessively chewing toys, doors, and window sills, or licking themselves, even to the point of injury,” Brinker says.
