I was told that as long as it is on occassion, that human food is ok.
I give Reyna pretty much anything without salt or seasonings. Although she has munched on a few salty potato chips that have made it to the floor (shes so fast). She gets cheese, ham, bread, chicken, mac n cheese, but SUPER small quantities every now and then. Aside from that, she eats her food like a champ. And is very healthy.
Who can say no to those puppy eyes! not me...
