Taz is a male 90 lb Golden Lab mix. He is neutered and current on all shots. Taz is housebroken and can sit, shake, high five, and lay down. He is well behaved in the house, but is is very aggressive toward most other dogs and most other people. When we got the dog from the shelter, we were told he had bone spurs in his lower spine. He was taking Meloxicam and Glucosamine supplements. Our vet believes it is a problem with his hind leg and not his back. As long as he stays on his medication and supplements, he doesn't appear to be in any pain. His loves squeaky toys, although we have yet to find one that will withstand his teeth longer than two or three minutes!
