But if he passed the regulations to become a therapy dog then I dont see the problem. Its older people its not like shes taking him to a sick kids hospital where they would be tugging on him.
Thunder bit me before and it was a accident ( I scared him and he attacked me and got my face) but he is the friendliest dog in the world and I know he wouldnt do anything like that again. I would take him to a nursing home and I would be 110% sure that all he would do is lick the peoples faces.
