Since the 2006 rabies watch there has been an update worth mentioning. Kiara the Husky died of old age. During this 5 year hiatus Chad has also lost Mollie the Collie to uterine cancer. Have your pet spayed or neutered.
Now we have Mongo. He's a mutt... So far he's been on his deathbed once or twice, had a run in with a porcupine and his face clawed up by the cat from the "Living Room Wars" video.
Good luck being Chad's dog. You're going to need it.
