Pet's info: Dog | Labrador Retriever | Male | neutered | 3 months and 24 days old | 36 lbs
We got our Labrador Retriever puppy neutered four days ago, and he also got microchipped. He has been wearing an Elizabethan collar, and now his right ear does not look right. It looks like it is wrinkled down the middle, almost as if it is limp. When I touch his ear, he acts like it is sore. The rest of his face looks completely normal and does not look droopy like his ear. Could the e-collar have temporarily damaged his ear, or could the microchip have interfered with a nerve?
