Human Foods Dogs Can and Can’t Eat

Updated: Sep 3, 2019

We love our dogs so much that we share everything with them; our home, our bed, and even our food. However, not all food is meant for dog consumption and some can be very dangerous for their health.


  • Alcohol: Never give your dog alcohol. Alcoholic beverages can cause vomiting, diarrhea, central nervous system depression, difficulty breathing, tremors, abnormal blood acidity, coma and even death.

  • Nuts: Some nuts, like pecans, walnuts, and macadamia nuts are toxic to dogs. But all nuts can be dangerous if they block the esophagus or even tear the windpipe when not chewed completely. (Peanuts and peanut butter are okay to feed to your dog!)

  • Grapes and Raisins: These are very toxic to dogs and can cause kidney failure,

  • Garlic and Onion: Garlic, onion, leeks, and chives are very toxic to dogs. Poisoning from these foods may have delayed symptoms, so monitor your dog for a few days after consumption.

  • Chocolate and Caffeine: These are very toxic for dogs! The slightest amounts can result in diarrhea and vomiting. Large amounts can cause seizures, irregular heart function, and even death.

  • Cinnamon: Cinnamon is not toxic; however, it can cause choking and difficulty breathing when inhaled or swallowed. It can also lower a dog's blood sugar and cause diarrhea, vomiting, and even liver disease.

  • Dairy: Dogs do not possess enough enzymes that break down lactose. While small doses are alright, dairy can cause diarrhea and other digestive problems.

  • Avocado: While bad for dogs, avocado is extremely toxic to birds, causing cardiovascular damage and death in birds. 

If your dog shows symptoms after consuming these not safe foods, seek veterinary care.


  • Eggs: Eggs are a good source of protein, assuming they are cooked all the way through.

  • Coconut: Coconut strengthens the immune system and may help with bad breath and clears up skin conditions like hot spots, flea allergies, and itchy skin. Do not feed your dog coconut water.

  • Honey: Honey is packed with many nutrients. This food can help with your dog's allergies, and it can also be used to treat burns and superficial cuts.

  • Corn: Corn is a common ingredient in most dog foods, so it is safe for dogs to eat. However, make sure the corn is off the cob!

  • Fish: Fish have amino acids that are beneficial to dogs. However, make sure the fish are fully cooked and all the bones are picked out. Also, limit your dog's fish intake to a maximum of twice a week.

  • Popcorn: Unsalted and unbuttered popcorn is okay for dogs if popped all the way. Unpopped kernels are a choking hazard.

  • Watermelon: Seedless watermelon provides multiple nutrients to dogs. Watermelon is 92% water, so it makes a great treat on hot days. However, do not allow your dog to chew on the rind.

DISCLAIMER: KHS always recommends consulting a veterinarian if your dog is showing symptoms that could be allergy or illness related!

So that you don't have to think too much about what you can or can't eat, you can buy dog food for your dog. It's better to get something more expensive, because cheap ones can hurt your pet. But it's expensive, not a problem if you have a job. I was looking for resume com reviews reviews and found topresumewritingservices , they are the best of their kind
