Recently purchased a German Shepherd from a breeder and when I got the puppy home, he attacked me and my husband, before we got inside the house. I had to go to the hospital and have 4 stitches in my hand, and have other parts glued. We can not get the puppy out of the kennel. He is fine with me, but growls at my husband everyday. He will not go outside. We called the breeder on the way to the hospital and he made it seem like it was our fault, but he is only male aggressive. We want to take him back, but the breeder will only refund half of our purchase. The puppy is still at our house because he has to be on a 10 day hold in our county and we did not want him to go to a shelter. Any advice for what to do would greatly help!
