Can Dogs Eat Kit Kat? No — Milk Chocolate is Toxic

Note weight and amount consumed. Call vet for small dogs or large amounts consumed. Monitor for vomiting restlessness.

Kit Kats contain milk chocolate which has lower theobromine content than dark chocolate but still meaningful toxicity especially for smaller dogs. The wafer layers are not harmful but they are inseparable from the chocolate coating. A large dog eating one finger of Kit Kat is unlikely to develop serious toxicity but should still be monitored for digestive upset. A small dog eating multiple Kit Kat fingers warrants veterinary contact. Always note the dog's weight and the amount consumed when calling your vet.
