So I've had my purebred Shepherd, Brady, for almost 2 weeks now. He is 9 weeks old. Does anyone have any good training tools or tips I should know of to try with him? Right now his biggest problem is peeing/pooping in my house and his biting. That's all normal, I've had dogs before but never a Shepherd. So I'm just looking for some guidance on what people have used with their pups. Thanks!
