He is 13 weeks old and has all his shots. The only shot he does not have yet is rabies because the breeder does not like giving it a rabies shot until they are about six months...Thank you for the suggestions I have a 4ft leash, the problem with biting the leash comes when I try to attach the leash to the back of his harness or when I'm trying to detach the leash. What ends up happening is that he rolls around on his back and continues to roll and roll to the point where it is impossible for me to detach it from him without trying to hold him still completely. As for playing with him, I play by making him sprint and stop for about an hour until he is tired. I throw the ball around sometimes, but when I do that's when he lies down and becomes more interested on the leash than the ball and starts chewing on it instead...that is when I squeak the ball to grab his attention and he plays with the ball for a minute before going back to the leash and so the cycle continues. I've only praised him with kibble (which he really likes) because all of the other treats I've tried (carrots, peanut butter, doggie treats at PETCO, cheerios) he leaves and does not like, so maybe its not a good enough treat to give him kibble? But I digress, I know that this involves a lot of patience and I get that, I'm just afraid to do the wrong thing (that's the part that frustrates me...not knowing what to do...I don't want Teddy to not like me!) He's a sweet dog that is is clearly acting like a puppy, and I love him and I want to do everything right for him, because he deserves it!
