Top Toxic Foods for Dogs in Your Kitchen

There are plenty of human food options that are safe to eat or even healthy snacks for your dog. One of the most important rules is treating human foods as treats and not meals for your dog. Moderation is extremely important when you give any human foods to your furry baby. However, this is not the case for toxic foods, as you should rather avoid altogether and at all costs. Be mindful of the fact that dogs do not have the stomach to digest just anything that is made for humans.

What You Should Know

If you accidentally fed your dog any of the dangerous foods listed below, call your vet right away. If you suspect that your dog might have ingested something themselves, call your vet. Do not wait to see any symptoms if you know they have consumed something they shouldn’t have.

Cooper Pet Care has compiled a list of the most potentially toxic foods for dogs that you can find in your kitchen. Find below the list with brief information on each one.
