What Can Dogs NOT Eat? 100+ Toxic Foods To Avoid


Have you ever wondered what can dogs NOT eat? As dog owners, we love to share our food with our furry companions. However, it’s important to be mindful of what we’re giving them, as certain human foods can be harmful to dogs. And just because I’m an animal communicator doesn’t mean that I don’t run into the same problems with my pets as everyone else!

What Can Dogs Not Eat: Understanding the Canine Diet

As I was steam cleaning the cantaloupe juice out of the carpet one morning (one of my dogs had snacked on the fruit that had been sitting on the kitchen countertop), I realized that I did not know whether cantaloupe was toxic for dogs. In fact, I wished I had an easily accessible catalog of toxic foods for dogs!

In case of an emergency, National Animal Poison Control is really helpful. Their website is here –> Animal Poison Control or call them at 800-426-4435. There is a $60, however, in times of need, this is no more than the typical co-pay for a human to go to the emergency room. My experience and that of my clients have all been very positive with this organization.

Please DO NOT post here that your dog has eaten something you are unsure of and ask if it is OK. We do not monitor this page on a daily basis. If you are questioning your dog’s behavior, CALL YOUR VET!

The Basics of a Dog’s Diet

Because of my line of work, I often have people calling me in a panic because their dog ate something and they don’t know what the potential consequences are. With that in mind, I have put the following list together, based on experience and research – and was especially surprised to learn about the dangers of avocados!

But first, do keep in mind dogs are omnivores. This means they can digest both plant-based and animal-based foods. However, their dietary needs are different from ours. Here’s a breakdown of what dogs should eat:

  • Protein: Protein is the building block of muscle and essential for healthy growth and development. Meat, poultry, fish, and eggs (cooked) are excellent sources of protein for dogs.
  • Carbohydrates: Carbohydrates provide energy for your dog’s daily activities. Whole grains, such as brown rice and oats, are healthy carbohydrate sources for dogs.
  • Fats: Fats are essential for nutrient absorption and energy production. Omega-3 fatty acids, found in fish oil, are particularly beneficial for dogs.
  • Vitamins and Minerals: Vitamins and minerals are crucial for various bodily functions, including digestion, immune system support, and bone health. A balanced diet should provide your dog with all the necessary vitamins and minerals.

What Human Foods Can Dogs NOT Eat?

While dogs may be tempted by the enticing aromas of human foods, many of these foods can be toxic to them. Here’s a list of what can dogs NOT eat:

NOTE: This in NOT an exhaustive list and it is certainly not meant to raise alarm – only to inform you about what to look out for. And notice… cantaloupe is not on the list! Hooray!

  • Baby Food: Can contain onion power which can be toxic to dogs.
  • Cat Food: Usually too high in protein and fats.
  • Eggs (raw): Raw eggs can cause salmonella poisoning in dogs. Dogs have a shorter digestive tract than humans and are not as likely to suffer from food poisoning, but it is still possible. If your dog has a partial blockage in their intestines where food can be trapped, e coli or salmonella could breed more easily. Egg white contains the protein ‘avidin’ which forms a stable and biologically inactive complex with biotin. The avidin in egg whites will tie up the biotin so it cannot be used by the dog.
  • Fat Trimmings: Fat trimmings can cause pancreatitis.
  • Iron: Human vitamin supplements containing iron can damage the lining of the digestive system and be toxic to other organs including the liver and kidneys.
  • Marijuana: Can depress the nervous system, cause vomiting, and changes in the heart rate.
  • Tobacco: Nausea, salivation, vomiting, tachycardia (rapid heartbeat).
  • Yeast Dough: Can expand and produce gas in the digestive system, causing pain and possible rupture of the stomach or intestines
