Can dogs eat breakfast cereal, and why?
Most breakfast cereals are sugary and best avoided; some contain toxic ingredients. High sugar, and chocolate or raisin cereals are toxic; check the ingredients carefully.
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 chocolate or raisin cereals are toxic; check the ingredients carefully.
