Can dogs eat ketchup, and why?
Ketchup is salty, sugary and often contains onion and garlic, so avoid it for dogs. Onion and garlic powder are toxic and the salt and sugar are unhealthy.
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
Onion and garlic powder are toxic and the salt and sugar are unhealthy.
