Dog literally jumping on the couch to bite the biscuit

This little old boy couldn't resist when a biscuit was put in front of his face, he couldn't help but try to bite it lol

My family adopted him few years ago; he was living on the street after he was abbandoned badly all of a sudden, for unknown reason, by the family who initially got him;

As you can see he's wearing a diaper like a little baby, 'cause the man got some incontince problems 😂
