Key risk

Why

Custard is sugary and full of dairy, so it is best avoided for dogs.

Can dogs eat custard, and why?

Custard is sugary and full of dairy, so it is best avoided for dogs. High sugar and lactose can cause stomach upset; not a suitable treat.

Dogs are omnivores, so most of their diet should be a complete, balanced dog food, with treats on top. They cope with a wide range of foods, but rich, fatty or sugary ones can cause stomach upset and, over time, weight gain or pancreatitis.

Warning — what to watch for

High sugar and lactose can cause stomach upset; not a suitable treat.

If your dog has eaten custard, don’t wait for symptoms — contact your vet immediately, or call the Animal PoisonLine on 01202 509000 (24/7, UK). Signs of a problem can include vomiting, diarrhoea, drooling, lethargy, tremors or loss of appetite.
