Obvious behavioral issues 

If you notice some behavioral problems in your dog, it means that they are stressed and try to defend themselves from what makes them anxious. 

“Most dogs will try to run away from something that scares them, but if they aren’t able to escape, or if they have learned that aggression can get them out of a situation, they may behave aggressively instead,” said Brinker. “Freezing happens where a dog spends a few extra moments deciding whether they want to fight or flee.”

In addition, one of the most common reactions of stressed dogs is fidgeting. “Fidgeting is a way for dogs to work off their excess energy without running away or attacking something,” Brinker says. “They may pace, pant, shake their body, lick or scratch themselves, yawn, dig, or do another behavior that doesn’t quite make sense in a particular situation.”
