Inappropriate urination

Unfortunately, dogs with chronic stress experience inappropriate urination, because stress hormones relax the bladder sphincters and urination will occur. 

“Defecation and anal gland expression may also occur,” Brinker said. “In the wild, urination, defecation, and anal gland expression are all defensive mechanisms that (hopefully) might make a predator back away and give a stressed animal the opportunity to escape a scary situation.”

However, if your dog experiences inappropriate urination, you should see your vet as soon as possible, because these problems can be caused by other diseases, not just stress.
