Top Foods That Are Toxic and Poisonous to Dogs and Why You Should Avoid Them

May 22, 2024

Dogs are devoted and affectionate friends, but they also have a knack for being inquisitive and adventurous. Occasionally, their curiosity may lead them to consume things that aren't safe for them. While we might savor certain human foods, these can be harmful or even fatal to our canine companions. In this article, we will explore some of the most prevalent foods that are toxic and poisonous to dogs and explain why they pose such dangers.

Avocado

Avocado is a well-loved fruit often regarded as a healthy fat source for humans, but it isn't safe for dogs. This is because avocado contains a toxin known as persin, which has the potential to cause vomiting, diarrhea, and pancreatitis in dogs. Persin is present in every part of the avocado plant, from the fruit and seed to the leaves and bark. Consequently, it's important to keep your dog away from any avocado-related products or plants.

Cherries

Cherries are sweet and juicy fruits that can be tempting for dogs, but they are not safe for them. Cherries contain cyanide, a potentially deadly chemical that can kill tissues by preventing them from using oxygen. Cyanide is found in the stems, leaves, and pits of cherries. The only part of a cherry that does not contain cyanide is the flesh around the pit, but it is still not recommended to feed it to your dog. Cherries can also pose a choking hazard if your dog swallows them whole or if the pit gets stuck in their throat.

Grapes and Raisins

Grapes and raisins are extremely harmful to dogs. Even a small amount can lead to sudden kidney failure, which might be fatal. While the exact way these fruits damage dogs’ kidneys isn't fully known, it appears to differ from one dog to another. Some dogs might experience symptoms like vomiting, diarrhea, lethargy, dehydration, and an increase in thirst and urination after consuming grapes or raisins. Others may not show any signs until it’s too late. Therefore, you should never feed your dog any grapes or raisins or leave them within your dog’s reach.

Tomatoes

Tomatoes are a staple in many dishes for humans, but they're not safe for dogs. They contain a compound called solanine, which is harmful to canines. Solanine is present in the green parts of the tomato plant, including the leaves, stems, and unripe tomatoes. Ingesting solanine can lead to digestive issues, neurological disorders, and heart problems in dogs. Although ripe tomatoes have lower levels of solanine compared to unripe ones, it's best to steer clear of giving them to your dog entirely.

Mushrooms

Mushrooms are a type of fungus that thrive in various settings. While some mushrooms are safe for humans to eat, others can be toxic. The same holds true for dogs. Certain mushrooms are harmless to dogs, whereas others have the potential to be lethal. Even experts often find it tough to accurately identify mushrooms. Therefore, it's crucial to neither intentionally feed your dog mushrooms nor allow them to consume any they might discover outdoors. Symptoms of mushroom poisoning in dogs include vomiting, diarrhea, abdominal pain, seizures, coma, and in severe cases, death.

Onions

Onions are frequently used to enhance the flavor of many human dishes, but they can be very dangerous for dogs. They contain a compound that harms dogs' red blood cells, leading to anemia. Anemia is a condition where the blood lacks enough oxygen-carrying cells, which can result in weakness, fatigue, pale gums, rapid breathing, and even collapse. Onions can be harmful to dogs in any form or amount. Therefore, it’s important to avoid giving your dog anything that has onion, onion powder, or onion flakes in it.

Other Toxic Foods

The list above is not all-encompassing. There are numerous other foods that can be harmful and dangerous to dogs, which you should also be mindful of. Some examples are:

  • Chocolate: Chocolate possesses caffeine and theobromine, both of which are stimulants that can lead to vomiting, diarrhea, tremors, seizures, heart issues, and even death in dogs.
  • Xylitol: An artificial sweetener, xylitol is commonly used in products like gum, candy, baked goods, toothpaste, and peanut butter. For dogs, xylitol poses significant risks, including sudden drops in blood sugar, liver failure, seizures, and even death.
  • Macadamia Nuts: These nuts can lead to symptoms like weakness, paralysis, vomiting, fever, and tremors in dogs.
  • Alcohol: Alcohol is a substance that can affect a dog's nervous system, liver, and kidneys. Ingesting alcohol can lead to vomiting, diarrhea, trouble breathing, coma, and even death in dogs.
  • Yeast Dough: A blend of flour, water, yeast, and sugar, yeast dough is commonly used for baking breads and pastries. However, when consumed by dogs, yeast dough can expand in their stomachs, leading to bloating, gas, discomfort, and even ruptures. Additionally, yeast dough can generate alcohol, which may cause similar adverse effects.

What Steps to Take if Your Dog Consumes Something Harmful

Discovering that your dog has ingested something poisonous can be incredibly stressful. It’s crucial to act quickly and calmly. Start by identifying the toxin your dog has eaten, then get in touch with your vet right away for advice. Making your dog vomit without professional guidance can be dangerous, so always consult a vet first. In the meantime, keep harmful items out of your dog’s reach to prevent such incidents.

If you think your dog has ingested a harmful substance, you need to move fast and contact your vet. Here are some steps you can follow:

  • Contact your vet, an emergency animal clinic, or an animal poison control center. They can guide you on the necessary steps and if it’s necessary to take your dog in for medical care.
  • Try to figure out what your dog consumed and the quantity. If you can, take the packaging or a sample of the item with you to the vet.
  • Do not force vomiting unless a professional advises it. Certain substances might cause greater damage if expelled than when remaining in the stomach.
  • Make sure your dog remains relaxed and at ease. Observe their vital signs and behavior, and notify the veterinarian of any variations.

How to Stop Your Dog from Consuming Harmful Foods.

The most effective method to stop your dog from consuming harmful foods is by ensuring they are kept out of reach. Here are a few pointers you can follow:

  • Place all human foods in sealed cabinets or containers that are out of your dog's reach.
  • Place any food remnants or wrappers in a secure trash bin that your dog cannot access or tip over.
  • Make sure not to leave any food out on the table, counter, or floor where your dog could grab it.
  • Avoid giving your dog any human foods without first confirming they are safe. If you're unsure, it’s best to stick with dog food and treats.
  • Learn about which foods are dangerous and harmful to dogs and understand the reasons why. Share this information with friends and family who have dogs or might bring their dogs when they visit you.

Conclusion

Dogs make fantastic companions, but they tend to be both curious and adventurous. Occasionally, they might consume something that's not safe for them, leading to serious issues. Many foods that are safe for humans can actually be toxic and dangerous for dogs, potentially causing a range of health problems or even being fatal. That's why it's crucial to monitor what your dog eats and to be mindful of what you leave within their reach. By adhering to the advice in this article, you can safeguard your dog from ingesting harmful foods, ensuring they remain healthy and happy.
