I buy the little 1/2 cup single servings of vanilla ice cream, and Foxy gets to lick the top and the empty cup when I'm done. Her eyes go as big as saucers when she sees you take one of those out of the freezer! She's never had a "problem" develop out of eating that small amount of ice cream.
We also made homemade ice cream once and let her try that, but that was much more ice cream (and much richer) than normal, and it gave her some issues later on...
