We have a 10 month old doberman puppy. He's really very well behaved most of the time.. but for some reason, when it comes to his biting we're having a really hard time. He doesn't chew anything he isn't supposed to. He doesn't bite any other people other than me and my boyfriend. He's even friendly with other animals. Sometimes he'll just get in a mood (while we're sitting watching tv or when I'm trying to walk around the house) and he will want to try to play by biting our hands, arms, feet, legs, clothes, shoes, pretty much anything he can get his teeth on really. We've had him for 8 1/2 months and let me just say this is not a new problem for him.. We've tried just about everything we can Google. We're a little lost in which direction to go now.. Any suggestions??
