Food safety
Can dogs eat plain cooked chicken?
Yes — fine in small amounts
Skinless, boneless and unseasoned. One of the best training treats there is.
How much
Small pieces
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.
