This is an important question to answer because dogs like to eat table scraps and garlic’s tempting smell makes them excited and interested in eating this Allium Sativum food. Let’s jump into it and clear all Myths regarding raw garlic, garlic powder, garlic oil, garlic supplements, garlic salt, garlic bread, garlic butter, garlic bologna, garlic cheese, garlic hummus, garlic juice, garlic knots, and minced garlic consumption in canines and felines.


Is Raw Garlic Bad for Dogs to Eat?

The short answer is Yes. But there are some other sides of the picture that I want you to consider. The amount of garlic consumed, the age of a dog, the weight of a dog, and the health matter a lot when we try to find the precious answer for this question. Before diving into explaining these factors affecting the toxicity of garlic in dogs, I would like to let you know;

How Garlic Causes Toxicity in Dogs?

Most probably you’re thinking that “why is garlic harmful to dogs”, don’t be panic because here in the following section I would briefly explain which ingredients (of garlic) promotes garlic toxicity in canines.

Garlic contains an ingredient, called n-propyl disulfide which a dog’s body cannot digest or dogs don’t possess certain digestive enzymes that are responsible for the digestion of disulfides or thiosulfates. While the human digestive system contains certain digestive enzymes that can easily break down (metabolite) all ingredients of garlic including thiosulfates or disulfides.

Hence, a human body can easily metabolite garlic while a dog’s body can’t metabolize all the ingredients of garlic and fails to poop out thiosulfates (present in garlic: a member of Allium Sativum family).

Disulfides and Thiosulfates Side Effects in Dogs

Garlic contains thiosulfates that are harmful to dogs and a dog’s digestive system cannot digest them. Thiosulfates don’t get out of a dog’s system completely and remain in the body that initiating toxicity.

How Thiosulfates (present in garlic) Causes Toxicity in Dogs?

Garlic contains five to ten times more thiosulfates than the other members of the Allium Sativum family. They bind with the red blood cells of a dog’s body and make clumps also known as Heinz bodies.

It changes the structure of red blood cells and a dog’s body starts assuming these Heinz bodies as an invader. Hence, the defense system of the body starts destroying these Heinz bodies (red blood cells attached with thiosulfates), and the process is called hemolysis. It increases the risks of hemolytic anemia (low blood count).

Red blood cells are responsible for the transportation of oxygen to all parts of a living body through blood. The destruction of red blood cells in a dog’s body reduces the oxygen levels (oxygen saturation: SPO2) which causes tiredness, weakness, fatigue, and other symptoms of anemia.

Signs and Symptoms of Hemolytic Anemia caused by Garlic toxicity in dogs

Below are the most common and observed effects of thiosulfates (present in garlic) poisoning in canines. Take an eye on them all and seek a veterinarian for immediate treatment;

Some pet owners observed good effects as they reported that using garlic as food for their dog boosts immunity, prevents infections, lowers cholesterol levels, and aids in maintaining heart health.

Age Factor

Surely, if you give garlic (even in tiny amounts) to a puppy. It will surely result in garlic poisoning in puppies. Young dogs that have a strong immune system and have an active lifestyle rarely build any side effects. So, you must avoid giving garlic to small dogs.


Japanese breeds like Shiba Inu, Chow chow, Akita Inu, etc are on the hit list. You should avoid garlic in these breeds because they are more prone to developing poisoning than any other dog breed.

Body Weight

This topic is controversial, however, I would try to explain it briefly. Some veterinarians and dog health experts believe that dogs with high body weight are less likely to develop garlic poisoning than dogs with low body weight.

Only a veterinarian may decide which amount of garlic is good for your pet. Some dog medicine experts believe that 3-7 grams of garlic are crucial for 20-40 pounds dogs. You must consult a veterinarian before taking garlic for your furry pale.
