As for obese pets ... oh ... I know one of those! His owners are overweight too. Every time they nibble on something ... there is Rocky nibbling on it too! They even give him beer :(
That was somewhat unfortunate for the dog. Drinking beer? Really? Isn't that count as an abuse or something?
It is difficult to think of Rocky as an abused dog. Despite the way his owners feed him, he is a very loved, well-looked after little dog. I put it down to ignorance :/
