Can Dogs Eat Garlic?

February 14, 2025

Garlic is a common ingredient in most delicacies around the globe. The spice is popular because of its medicinal benefits. The sweet and tasty aroma of roasting garlic can be tempting for most pets. Often, your furry friend may rush into the kitchen to see what's cooking or stare at you directly in the eyes, trying to convince you to share the garlic feast you are enjoying. But can dogs eat garlic? Read on to find out.

Is Garlic Safe for Dogs?

Garlic is renowned for its numerous vitamins and minerals. According to an article written by PetMD, it prevents the formation of blood clots and tumors. But can dogs eat garlic, or is it toxic? The answer to this question is debated in the pet world, and many articles exist. While most research warns that garlic is poisonous to dogs, some scientists argue that it may offer minor benefits. This article strives to answer the question, “Is garlic bad for dogs?” It explores garlic’s effects on dogs, dissecting if it has any benefits and how canine parents can keep their pets from potential risks.

Understanding Garlic: What Makes It a Concern for Dogs

You can call it the stinking rose, rustic treacle, or even the nectar of the gods. Garlic is a member of the genus Allium. It shares its lineage with onions and leeks. According to Cornell Feline Health Center research, food seasoned with garlic should be kept away from your furry friend. The popular spice contains N-propyl disulfides and thiosulphates. These compounds are toxic when metabolized by dogs, causing damage to red blood cells that supply oxygen around the body. Your pet may appear lethargic and weak because of insufficient blood. If left untreated, this can result in anemia.

In addition, garlic can also cause gastrointestinal irritation. When your canine friend consumes it in high quantities, they can suffer from:

  • Diarrhea

  • Vomiting

  • Lack of appetite

  • Dehydration

  • Depression

  • Jaundice

However, there is a lot of mixed information available online. Some sources say a very small amount of garlic is beneficial to dogs. For example, PetMD says feeding your puppy garlic in low dosages can be beneficial because it is rich in healthy components like amino acids, zinc, potassium, and more.

Is Garlic Toxic to Dogs? Understanding the Risks

There's no doubt that the sweet smell of garlic can be very tempting for a man's best friend. Your dog may gaze at you with pleading eyes, hoping for a taste of that aromatic dish. Naturally, as a caring dog parent, you might wonder, “Is garlic toxic to dogs?” 

Here’s how garlic affects dogs:

  • Hemolytic Anemia Risk: Ingesting cooked, raw, dehydrated, or granulated garlic can cause acute hemolytic anemia in dogs. Garlic boasts sulfur-containing oxidants, which are responsible for hemolysis. The compounds destroy the red blood cells, ultimately resulting in anemia (the deficiency of red blood cells).

  • Gastrointestinal Issues: Dogs and garlic are not the perfect match. Treats and food containing this spice can cause gastrointestinal problems. While the acute symptoms of garlic poisoning may take time to show, signs like diarrhea, vomiting, and lack of appetite could indicate a problem.

  • Organ Damage: In severe cases, garlic poisoning can damage your pup's organs, resulting in death. If your dog consumes too much garlic, immediately contact a veterinarian, even if they look okay.

Factors That Influence Toxicity

The following factors can influence the level of garlic poisoning in dogs: 

  • Size and breed of the dog: Yes, the size of the dog matters. For example, the Great Dane may not be fazed by a bit of garlic, but it could be a direct ticket to the vet for a Chihuahua. Also, some dog breeds are more sensitive to garlic poisoning than others.

  • Amount of garlic consumed: Scientific studies conducted by NLM-NCBI found that a dog has to eat approximately 15-30 grams of garlic per kilogram in body weight to experience poisoning.

  • Raw vs. cooked garlic: Raw garlic has a strong flavor and pungent scent. It retains more sulfur-containing compounds than cooked garlic, making it more dangerous.

Symptoms of Garlic Poisoning in Dogs

We recommend that you contact a vet immediately if you suspect your pooch has got their paws on garlic. Also, remember that it may take a few days for the symptoms to appear, depending on the amount of garlic consumed and the dog's size. Here are some of the common symptoms of garlic poisoning in dogs:

  • Vomiting

  • Diarrhea

  • Lethargy

  • Weakness

  • Drooling

  • Abdominal Pain

  • Pale gums

  • Rapid breathing

What to Do If Your Dog Eats Garlic

Do not wait to see the signs of toxicity if your dog has consumed a lot of garlic. Only a veterinarian can monitor symptoms closely and determine if your furry child needs medical treatment. A trip to the vet can be the difference between a scare and a tragedy. In severe cases, the vet might perform a blood test to check for anemia and offer IV fluids and supportive care.

Resist the temptation of inducing vomiting even if you have caught your dog red-pawed with garlic. Instead, call your vet ASAP! And note the amount. This will help the veterinarian determine the right course of action. Activated charcoal can also absorb toxins, but doing so requires some skill. If you are unsure, call your vet. They'll guide you on the steps of administering activated charcoal.

Garlic in Dog Food and Supplements: Are Small Amounts Safe?

Some dog food and supplements contain garlic at the lowest therapeutic doses: the tiny dose benefits immune function and your pet's overall health. However, mainstream veterinary organizations like the American Veterinary Medical Association and American Animal Hospital Association (AAHA) caution against feeding your dog garlic. Their main concern is the N-propyl disulfides and thiosulphate compounds that can be found in even small amounts of garlic. The safest approach will be to keep garlic far away from your dog. Feeding your pet healthy dog food ensures they receive the necessary vitamins and minerals.

Safe Alternatives to Garlic for Dogs

Are there any safe alternatives to garlic for dogs? Yes, several nutrient-rich fruits and vegetables serve as healthy and safe alternatives to garlic. Here are some wholesome treats that your pup can enjoy:

Healthy Herbs and Spices 

  • Turmeric: Has anti-inflammatory benefits. It is excellent for senior dogs because it supports joint health.

  • Ginger: Aids your dog in digestion and cures nausea.

  • Parsley: Offers essential vitamins and minerals. It also freshens your dog’s breath.

Conclusion

Garlic, even in small quantities, can be toxic to your dog. The severity of poisoning depends on your dog's size, breed, age, and general health. Prevent accidental ingestion by not feeding your dog human leftover food that may contain garlic in some form. Also, store garlic cloves in sealed containers and on high shelves outside your pet's reach. Always contact your vet immediately for guidance if you suspect your dog has consumed garlic.
