Ddog and I sometimes meet with a friend and her dog. With her particular dog, mine plays differently to when he's with other dogs.
Both dogs have their mouths open, teeth on show but don't seem aggressive while doing it. Is this normal? After they've been doing this a while it does sometimes then turn into snarling. Should we interfere and separate them?
Really not sure where the line is between playing and fighting. My dog is 1 year old and hers is 2.
