Mix some plain yogurt with some peanut butter for flavor and freeze in paper cups. Once frozen, tear off the paper cup and give the dogs a frozen treat.
Same sort of thing-
A few biscuits or liver treats in the bottom of a plastic cup beat egg and yogurt together, pour in and add a small dollop of peanut but in the middle and allow to sink to centre. Freeze, cut away cup of pop contents out.
