I feel that I am a responsible breeder. I have not breed a lot of dogs, I mainly did it when people I knew wanted a pup. Another one on the dogs that I sold last fall has come back to me. I love Jackson and he is not going anywhere. Max and Jackson get along very well. Padro came back to me because he tried to bite the owner and another family member. Knowing the dogs background I figured there must be a reason. I figured it out the first night. He is DEAF, I'm not sure how long he has been like this. He is too smart and behaves basically like a hearing dog. He was recently neutered, could that cause it? The biting just started. If you startle him he gets defensive. I am careful how I approach him from behind or how I wake him up. He is confused at not being able to hear. He is not sure if the other dogs are barking to play or to fight. I have him responding to hand signals already. I have 2 heelers now and cannot keep him. I took him to find him a home that he fits into. Now it will be more difficult. He is so sweet and smart, I cannot think of putting him down. If anyone can help him out, please contact me.
