I bought a mini schnauzer the other day. He is 8 weeks old. He is good natured he is even good around the baby. The problem is He torments my girlfriends cat. The cat is full grown but has had her front claws removed. How do I stop him from atacking the cat? He just looks at me when I say NO and then goes right back to the cat. I want to break him of this before he gets any bigger. Other than that he is a great little dog. Has very few accidents in the house and is very playfull and loving to humans.
