Who does that to their pet?
The chihuahua is already an incredibly shitty hyper-cat (only med-large breeds quality as dogs)... but to keep it on a steady diet of beer and doughnuts is DOG ABUSE.
Then to praise and coddle it because of its sluggish, degenerated state is mind blowing.
I hope he's just fattening it up - because gravy aside, this dog is not worth its weight in anything.
