Strange Behavior 18 Months

by Maureen
(Ontario)

Hi,
We have an 18 month old neutered male. He is very well socialized… hasn't met a person or other dog so far that he hasn't liked. We haven't seen him display aggression at all. He is definitely high energy… but we run him around alot, so we think he is getting enough exercise. I would say he is mostly obedient… although he definitely tries to get attention by running off with things.

Anyway… one night last week I was watching TV and he came over and started humping my legs… which he has never done before. Later that night he was lying down and my husband called him to go to his bed, and he didn't come. He went over to get him and grabbed him by his collar (not in a forceful way), and Digger turned his head and bit him on the hand… breaking skin. My husband grabbed him by the scruff of his neck and held him down but Digger did not become submissive… he was still mad. Eventually my husband put him in his bed. Next day it was like nothing happened… he was as lovable and fun as usual. And nothing similar has happened since.

Any ideas on this. It was rather worrisome to us, since we want to be able to trust him.

Thanks for your help,
Maureen
