He's always been kind of possessive about people. When we first met him, he snuggled on my lap and fell asleep. One of his litter mates tried to squirm in, and he growled at her. I didn't think too much of it, but that was exactly what's he like. So if he's sitting on my husband's lap, he doesn't like it when someone approaches. When he stays at his breeder's he plays well with the other dogs, but he also likes to snuggle on her lap...she says he'll share, but he's not moving. He's just not the typical "friendly to everyone" Cavalier personality like Teddy was. He bit my son a couple weeks ago. He rumbles first. It's just different. Then he'll go 3 weeks and never do this. He doesn't it when our house cleaner stands over him and tries to pet him. It seems like he's going on the offense to try to protect himself, but no one is actually threatening him. He's very reactive toward other dogs and cars on his daily walks. Nothing is new, it's just him, but I'd like to know what's going on on his dog mind so we could help him chill and be more trusting.
