Toxic Dog Food & Treats List

Toxic Dog Food & Treats List

You may have heard that many foods can poison your dog, but did you know many plants are toxic to dogs as well? Today, our vets in Blountville discuss a list of toxic food, treats, and plants for dogs.

Dogs and Human Food

Dogs are clever. Sometimes they embrace human foods they shouldn't. Thus, it's important to understand which of the foods we enjoy are toxic to dogs. 

Dogs don't digest food like humans. That's why foods and plants that are harmless to humans can be deadly to dogs.

Foods You Should Never Give Your Dog

This list is a summary of some of the most common foods toxic to dogs. To find out more about which foods are toxic to dogs, speak to your Blountville vet.

Garlic, Onions, Shallots, and Chives

Garlic, onions, shallots, and chives are toxic to dogs, whether raw or cooked. They have substances that may cause anemia and damage red blood cells. Signs of illness may take several days to manifest. 


Xylitol, an artificial sweetener in chewing gum, can cause vomiting, loss of coordination, seizures, liver failure, and hypoglycemia. These can lead to loss of consciousness or even death in extreme cases.

Macadamia Nuts

Macadamia nuts have a toxin that can affect your dog’s muscles and nervous system. Your dog can suffer weakness, swollen limbs, and panting.


Chocolate, particularly dark chocolate, has a stimulant called theobromine which can cause kidney failure.

Cooked Bones

Cooked bones splinter and can cause the gut to perforate. This can cause peritonitis or even death. So while not necessarily toxic to dogs, you should take care to never feed them cooked bones.

What plants can poison my dog?

Many plants can make your dog sick. You should always keep your dog from chewing on any plants or vegetation outside. What can be safe and beautiful for you can be toxic for your dog.

Below, our vets list some of the plants toxic to your dog. If your dog does eat any of these, bring them to our emergency animal hospital in Blountville.


Milkweed is a beautiful plant, but it can have severe effects on your dog's health. It causes rapid or weak pulse, difficulty breathing, diarrhea, nausea, and even death.


Mistletoe is found in many homes during the winter holidays, but if you have a dog, you should beware. Mistletoe causes abdominal pain, diarrhea, vomiting, and drooling. In severe cases, it causes collapse, seizures, abnormal heart rate, low blood pressure, and in some serious cases, death. 


Foxglove can have serious effects on your dog. But the severity of the symptoms can vary based on how much foxglove your dog eats. Symptoms can include tremors, weakness, diarrhea, vomiting, cardiac arrhythmias, seizures, heart failure, and death.


Tulips are one of the most popular spring flowers. If you are a dog owner, however, we suggest keeping tulips out of your yard. The petals on tulips upset your dog's stomach, and the bulb is even more toxic. It can cause an upset stomach, loss of appetite, and depression.

Treating Poisoned Dogs

Treatment for your dog will depend on the food or plant they ate. The treatments your vet could perform include:

  • Antidotes (if one is available for the specific plant)
  • Stomach pumping
  • Induced vomiting
Always call your vet as soon as you suspect your dog has eaten something toxic. Your veterinarian will give you instructions to help your dog while on the way to the clinic. Do not induce vomiting unless a veterinarian tells you to.

If you suspect your dog has been poisoned, contact our Blountville hospital right away! Time may be of the essence.
