Hi everyone. I need some help with my puppy. He's a Labrador Cross breed and he's only 8 weeks old. He was abandoned on the streets and I rehabilitated him. He is very hyper and energetic when he is up and awake. He takes good naps and plays well with children. And is almost poop trained. The problem is he tends to go overboard and starts biting when playing. and he whines a lot even after he has been fed well. I cud really use some guidance in this matter as this is my first time with a puppy.
