Zeus is a VERY sweet dog. However, we have a small dog and he does NOT like him. He's extremely aggressive toward him and it's not good and we're afraid he is going to hurt our small dog and our small dog came first so we need him gone ASAP. He's fantastic with big dogs, adults, and kids. Just not small dogs. I'm asking $600 because that is what I paid for him but best offer works too. He needs to be neutered.
