Can dogs eat liver?
Yes, but be careful
A brilliant training treat, but very high in vitamin A. Keep it to small amounts rather than a regular meal.
Being honest about this
Dogs differ, and amount matters — a crumb of something rich is not the same as half a packet. Treats of any kind should stay under a tenth of what your dog eats in a day. If you're unsure, your vet would far rather take the call.
