My pup, Finley, just had his three month b-day on the 16th. I was just wondering when will the biting stop? I know he's teething and can't help it but sometimes he gets ya and boy does it hurt. Those baby teeth are like little daggers. I always try to have a toy or bone to replace my hand with but I'm not always sucessful. Should I stop him from doing it? I don't wanna make him stop doing something that is natural to him obviosuly, but I don't want him to think biting is ok. Basically, I just wanna know when is it normal for them to stop biting and at what point should I be concerned? Also, how do you guys feel about training a dog on the treadmill? It seems to me that it would be a great way for him to get exercise when a walk isn't an option, but I just want to make sure it's not harmful to him in any way.
