Food safety
Can dogs eat raw egg?
Yes, but be careful
Salmonella risk, and raw whites can interfere with a B vitamin. Cooked plain egg is the easy alternative.
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.
