I'm not going to say I told you so. That never helps

. Jadabug is right. He is so young and patience is key. He will be the loving companion you wanted but it takes time and bonding. Puppies need lots of training. Housebreaking is not easy but can be done. DJ will have to go every single time he eats or drinks. If he is in his playpen and has to go nature will take it's course. It's not his fault if he can't get out to go when nature calls. Pad training takes time and almost constant watching over him. Biting while playing is natural at his age, too. It will just take time, understanding and lots of loving. Hang in there and try not to lose your temper with him. You're all he's got and eventually he will just want to please you.
