5 Common Foods that Can Poison your Dog #poisonpreventionawareness

This is a sponsored post.

March is Poison Prevention Awareness Month!  There is a page on Keep the Tail Wagging that lists foods and items that are poisonous for dogs, but I think it’s important to repeat the list every now and then simply, because we almost made the mistake of feeding our dogs grapes, not realizing that they’re toxic.  Now, we Google everything.

I want to thank the folks over at UK’s Dogs Corner for submitting this fantastic list to help us keep our dogs healthy and safe!

5 Common Foods that Can Poison your Dog

My dog’s a true master of the art of guilt-tripping. It’s hard to say no to those big brown eyes and wagging tail as he pleads for just a morsel of the dinner I’m enjoying. I’ll happily share my greens and fresh grains, but there’s a lot of people food that’s toxic for dogs. In fact, seemingly harmless healthy treats like grapes and raisins can be poisonous to dogs, which is why it’s important to find out more about what you can and can’t feed your dog. In an ideal world, we’d all strictly stick to the prescribed kibble but dogs are excellent beggars, and highly skilled at getting into foods they shouldn’t.  The following are five foods that can poison your dog, and which should be kept well out of reach!

1. Chocolate 

Although most people already know that chocolate is poisonous to dogs, I’m going to repeat it because it’s important. There’s a compound called theobromine in all forms of chocolate which is toxic to dogs, causing indigestion, excessive thirst, and seizures. In high doses, chocolate can even be fatal. The most dangerous forms are dark and baking chocolate.

2. Grapes and Raisins

Grapes may seem like naturally healthy treats for dogs, but they are unsuitable and even poisonous. Even a handful of grapes can make a dog sick, and larger doses can lead to kidney failure. One early sign of poisoning is repeated vomiting, with later signs of illness including lethargy. If your pooch seems sluggish after eating raisins, take him to the vet. You’ll want to keep your fruit bowl well out of reach.

3. Macadamia Nuts

Foods containing macadamia nuts are a no-no for dogs, with chocolate macadamia-nut cookies the worst offenders. As few as six nuts can make a dog sick. Symptoms of macadamia nut poisoning could include muscle tremors, vomiting, paralysis, and rapid heart rate. If you notice your dog shivering even when wearing dog coats, it’s time to see the doctor.

4. Avocado

There’s nothing more delicious than guacamole, but it can be dangerous to dogs. There’s a substance known as persin which is located in the fruit, leaves, and seeds of avocado plants. Most people can tolerate persin, but dogs can’t. A small amount of avocado is probably harmless but in larger doses this can lead to indigestion and symptoms of poisoning. If you grow avocado trees at home, be sure to keep them behind a gate so that your dog can’t eat any part of the plant.

5. Onions and Garlic

If you adhere to the Mediterranean diet, you may put onions and garlic in everything. Unfortunately, food cooked with onions and garlic should be kept away from dogs at all costs! Even onion powder or dehydrated garlic can be poisonous to dogs, destroying their red blood cells and leading to anemia  Although the occasional small dose won’t kill a dog, larger amounts could cause illness.

As you can see, there are plenty of foods that are healthy for people but toxic for dogs. It’s always a good idea to speak to your vet if in doubt or simply stick to food that has been designed specifically to meet a dog’s nutritional requirements.

Have you made the mistake of feeding your dog something that wasn’t great for them?


  1. Not disputing the others but I do challenge the statements about avocados…I’ve always allowed my dogs to have small amounts of avocado flesh when my tree is producing, to no ill effect…and what about commercial food Avoderm?
    The respected Dogfood Advisor website has this to say:

    “Supporters claim the ingredient to be nutrient rich and beneficial to a dog’s skin and coat — while others worry over what are mostly unsubstantiated concerns over potential toxicity.
    These fears appear to originate from a 1984 study in which goats (not dogs) consumed the leaves (not the fruit) of the Guatemalan (not the Mexican) avocado and became ill.4
    Based upon our own review of the literature, it is our opinion that the anxiety over avocado ingredients in dog food appears to be unjustified.”

    • Thanks for sharing that; I’ve heard both ways; that avocados are safe and great for dogs and that the persin in avocados is toxic. Whenever I come across something that has two stories, I tend to shy away from it, better safe than sorry. We have no experience with giving our dogs avocados or food with this as an ingredient. There are so many other foods out there that our dogs can enjoy that I don’t worry to much about it.

      But I love love love avocado for myself; I eat them with tomatoes, salt and pepper. Yummm – I know what’s on the menu tonight.

  2. Great post Kimberly! What about chicken broth or beef broth for frozen treats? I saw the beef broth ingredients had onion and garlic on it :( Do you know if that is safe or not?

    • I know people who feed their dogs chicken broth from the can and have had no issues; I think it’s about the percentage of ingredients. I’m just not certain, because I then ask myself if toxicity can build up over time even if delivered in small doses; so I don’t feed our dogs broth. Instead, I make our own when I make pot roast or boil turkey (Rigo is allergic to chicken).

      • Thanks Kimberly! I need to research a bit more about the beef broth. Even broth from my pot roast, turkey or chicken is still seasoned with whatever I put on it. Maybe something to stay away from for me too :(

  3. very interesting….for years I have heard folks advocating garlic in their dogs food as a parasite remedy or a way to at least decrease them however I personally never tried it. Now Im curious to research a little more into it. Thanks for the article!

    • I asked a few vets about that and they said that it doesn’t work. I use a product by Bright Eyes Pet Wellness to repel fleas and ticks:

      I’ve seen the products your talking about at the pet store; I’m certain that it works for someone or they wouldn’t sell it. Someone once told me that the amount of garlic was safe for dogs, but I don’t want to take a chance.

  4. Thanks for this post Kimberly! You would think that people know about things like chocolate but a few years ago Belle was staying with a friend who didn’t think it was a big deal. She left out a tray of triple chocolate brownies and all the dogs are them. Belle was hospitalized with seizures and it was one of the scariest nights of both our lives. It’s so important to share this information regularly.

    • So true! I’m always astounded by the people who don’t know. I really worry about kids, because not only do they not know, but sometimes when you tell them they don’t believe you.

      By the way, I mentioned Belle on today’s post :) – I think it’s getting creepy now; I need to stop stalking her.
