#1 – Whining
A stressed German Shepherd Dog often whines a lot. If your dog is whining and you know he doesn’t have to go outside to go potty, he may be stressed. He may also bark.

#2 – Pacing
German Shepherd Dogs are a herding breed, meaning they were used to keep the herd of grazing animals in a certain area of the pasture. When they get stressed or anxious, they may revert to this instinct, which includes pacing the perimeter of the room, yard, etc. If they are on leash, they may pace back and forth in front of or behind you.

#3 – Lip Licking
Lip licking is a common sign of stress. Your German Shepherd Dog may lip lick and then yawn when he is stressed. It’s usually a slower lip lick than when they are tasting something good. It can also look like a “flick” where the tongue come out and goes back in without actually licking their lips.
#4 – Ears Down
While most German Shepherd Dogs have erect or partially erect ears, a stressed one will often have lowered ears. Sometimes, they flatten completely against their head.

#5 – Whale Eye
This is something a lot of anxious dogs will do and it’s easy to spot on most German Shepherd Dogs because of their dark coat. “Whale eye” is when your dog’s eye bulge and the white around the iris is visible. This is a definite sign of a stressed or anxious dog.
