Although garlic is not as poisonous to dogs as some other foods, it can still be harmful if your dog ingests too much. The Allium species of plants, which includes garlic, onion, leeks, and chives, contain compounds that are toxic to dogs and can cause anemia. If you think your dog has eaten garlic, it’s important to watch for signs of garlic poisoning and to contact your veterinarian right away.

How Much Garlic Is Toxic To Dogs?

Dogs can be toxic to garlic. The toxicity of garlic to dogs is dependent on the form of garlic, the amount of garlic ingested, and the size and health of the dog. All forms of garlic are toxic to dogs, including raw garlic, cooked garlic, and powdered garlic. A small amount of garlic is not likely to be toxic to a dog, but a large amount of garlic can be dangerous.

The Risks Of Feeding Garlic To Dogs

While garlic is not considered toxic to dogs, there are some risks associated with feeding garlic to your dog. The biggest concern with feeding garlic to dogs is the potential for anemia. Garlic contains a compound called thiosulfate, which can damage red blood cells and cause anemia in dogs. If you are concerned that your dog has eaten garlic, contact your veterinarian immediately.

How To Safely Feed Garlic To Dogs

It’s common for people to want to feed their dogs garlic. After all, garlic is healthy for us, so it stands to reason that it would be healthy for our canine companions, too. However, it’s important to be aware that garlic can be toxic to dogs in large quantities. Here’s what you need to know about feeding garlic to your dog safely.

When it comes to feeding garlic to dogs, the general rule of thumb is that one clove of garlic per ten pounds of body weight is considered safe. So, if you have a small dog that weighs ten pounds, they can safely eat one clove of garlic. However, if you have a large dog that weighs 100 pounds, they should not eat more than ten cloves of garlic. Eating more than this amount can cause gastrointestinal upset and could even lead to anemia.

If you’re not sure how much garlic your dog should eat, it’s best to err on the side of caution and give them less rather than more. You can always give them more next time if they seem uninterested in their food or are still hungry after eating their meal.

When it comes to feeding your dog garlic, there are a few different ways you can do it. You can add some chopped garlic to their food, or you can give them a whole clove of garlic to chew on. You can also purchase garlic supplements from your local pet store.

Symptoms Of Garlic Toxicity In Dogs

If you think your dog may have eaten garlic, watch for symptoms like vomiting, diarrhea, lethargy, loss of appetite and redness of the skin. These can occur within a few hours or a few days after eating the garlic, depending on the amount that was consumed. If you notice any of these symptoms, call your vet immediately. A blood test can confirm garlic toxicity and your vet will likely recommend treatment to prevent further damage.

Treatment For Garlic Toxicity In Dogs

If your dog has eaten garlic, onions, chives, or leeks, contact your veterinarian immediately, as these foods can be toxic to dogs. The level of toxicity will depend on the amount consumed and the size of your dog. Small dogs and puppies are more likely to be affected by garlic toxicity than larger dogs.

If you think your dog has consumed a toxic amount of garlic, call your veterinarian or the Pet Poison Helpline at (855) 764-7661 for guidance.

Prevention Of Garlic Toxicity In Dogs

Most dogs will recover fully from garlic toxicity with no long-term effects if the exposure is caught early and treated promptly. The best way to prevent garlic toxicity in dogs is to avoid feeding them foods that contain garlic, onions, or chives. If you must feed your dog a food that contains these ingredients, make sure to do so in moderation and consult with your veterinarian first.


Puppies and young dogs are more susceptible to the effects of garlic toxicity than adult dogs. Symptoms of garlic toxicity include vomiting, diarrhea, lethargy, anorexia, and black tarry stools. If you suspect that your dog has ingested garlic, call your veterinarian immediately.


Is garlic bad for dogs?

First of all, it’s important to know that garlic is a member of the onion family and, like onions, can be toxic to dogs. The toxicity level of garlic is much lower than that of onions, however, and it would take a lot of garlic — at least 1/2 pound per 50 pounds of body weight — to cause toxicosis in dogs. A dog would have to eat an extraordinary amount of garlic for it to be poisonous. Small amounts of garlic may cause gastrointestinal upset (such as vomiting and/or diarrhea), but is not likely to cause toxicity. If your dog has eaten a lot of garlic, call your veterinarian or the pet poison hotline immediately.


There is no definitive answer to this question as it depends on a number of factors, including the size and breed of your dog, as well as the age and health of your pet. Some dogs may be more sensitive to garlic than others, so it is always best to err on the side of caution.

If you are concerned that your dog has consumed too much garlic, look for symptoms such as vomiting, diarrhea, lethargy, loss of appetite or difficulty breathing. If you see any of these signs, call your veterinarian immediately.
