I haven't givin the pups any, probably due to the fact that I don't eat sweets so I never have them around. Even on Valentine's if I end up with chocolate the kids will eat it, and they don't share to well lol.
Oscar will usually eat the chocholate that doesn't make it in Kaitlyns mouth. Then if Kaitlyns hands are chocolately she will make Oscar lick her hands. I have found that a little bite of the candy bar chocolate doesn't hurt him. But once he got ahold of some fudge and he threw up like 3 times.
