How old is your dog.. is he/she 2 1/2 yrs of age? If so, your dog is coming of age and maturing. AB's are known for being dog aggressive, esp towards the same sex. THey can also be toy and food aggressive, as this is a dominant breed. If you are not planning on breeding your AB, you might spay or neuter. It's no guarantee it will help the behavior, but might possibly cut down on some of those raging hormones. If the two dogs no longer get along, for safety reasons, you might want to just keep them apart. There is a reason why the AB attacked. Small dog breeds often have big attitudes. Something the small dog is doing might be setting your AB off. Because of the size difference, I would definitely keep them seperated. If they both stay inside, crate training should be a must if you haven't already done so. Just keeping them apart should help by allowing each dog to have their own time with you etc. just incase there are any jealousy issues going on. Good luck!
