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.
