A few small cubes of plain, cooked yam are perfectly safe for a dog that size. As a general rule, treats like this should make up no more than 10% of your dog's daily calories to avoid digestive upset or weight gain. A whole large yam would be too much and could cause a stomach ache or diarrhea. If they've had a sensible amount, just offer water and monitor them.

Cooked plain. Not the same vegetable as sweet potato, but equally safe.
