Orion so far has been a great pup, sleeps through the night, potty training is going well and he's catching on to what sit and come mean. My only issue is that during play with his toys he gets super growly especially if playing tug-of-war with me or his 6 month old australian shepherd friend, Finn. We haven't had too many biting problems and when he's getting overly nippy with Finn we correct him on it, the only thing is that he growls like a monster when he's got toys in his mouth. It looks like typical puppy play and you can touch his body or the toy and he doesn't bite you or growl actually AT you but he sounds like an absolute maniac. He also does the growly thing when hopping around trying to get your to play, rather than barking, even without a toy. He really doesn't bark much yet, just the snarly noises. Is this something I should worry about or do some puppies just sound like monsters when they play? Will he grow out of it? He doesn't seem to act aggressive, he just sound like it, mainly when he's really excited.
