Pups ear folded in half .

Lincoln 's ear is back and folded in half like it has a crease down the middle.
Anyone seen this before?
What could it be?

 

Possibly teething. The ears can be a bit different in posture when the teeth are starting to get sore.

 

Okay thanks. It wasn't like that when we first got him. Hopefully it will straighten out.

 

They usually do

 

Thank you...
