Ok I really love this dog but the biting has to stop. I know it's July the 4th and fireworks are going off but he just bit my 5 year old on the leg and left a mark didn't bleed but still...not to mention all the clothes that have been ruined. We have rawrides everywhere, kongs and my family room is cluttered with dog toys. He gets 2 20 minute walks a day and lots of attention. I'm lost I don't know what to do?? Any ideas? I'm starting class with him on the 7th. He's 14 weeks and big alreay he's about 23lbs...SO I can NOT have a big biting dog!! I need help!!!
