Garlic Dangerous or healthy for my dog?


The world of companion animals has diversified greatly today, however, pets par excellence remain the dog and cat. Although the nature of both animals is completely different, they need some care that is similar, such as adequate food, companionship and affection, to follow the vaccination program established in each case and periodic veterinary reviews.

In addition, both dogs and cats run the risk of infestation by parasites, both internal and external, which we must perceive soon and treat properly as they can lead to different complications. Increasingly, owners are looking for natural remedies that can solve these types of situations, for this reason, in this Animal Expert article we talk about garlic to deworm dogs and cats.

Is garlic toxic?

Garlic is generally considered a prohibited food for dogs and at the same time a prohibited food for cats due to the study of Lee, Yamato, Tajima, Kuraoka, Omae, Maede, "Hematologic changes associated with the appearance of eccentrocytes after intragastric administration of garlic extract to dogs" American Journal of Veterinary Research, November 2000.

The truth is to say that garlic contains a toxic component called n-propyldisulfide, which in large concentrations can damage our pet's body cells. However, in this experiment, large amounts of garlic (from 5 ml to 1.25 ml of whole and raw garlic extract were used for each kilo of weight) directly intragastrically to four adult dogs, for seven days, which gave them caused Heinz body anemia. Therefore, according to this study, we should feed a 20 kilogram dog with 22 garlic cloves daily (approximately) for a month for this type of anemia to occur.

On the contrary, the publication of the article "Garlic: Friend or Foe?" from the Dogs Naturally Magazine, April 2014 argues that In small quantities Garlic itself is a potent antiparasitic in moderate amounts, in addition to offering many other benefits to the body of our dogs and cats.

Likewise, in 2006, the Institute of Veterinary Pharmacology and Toxicology of the University of Zurich determined that the toxic dose of garlic is 5 grams per kilo of body weight. Given that a clove of garlic can weigh 2 to 3 grams, a dog of the Pekingese breed should ingest more than 5 cloves of garlic a day to end up suffering from anemia that the component mentioned above causes. We can conclude that the moderate and rational consumption Garlic is not toxic to our pets.

Properties of garlic to deworm our pets

Garlic is the food medicine par excellence, It not only has multiple beneficial properties for us, but also for our pets: it is an antibiotic, antiplatelet, protects the cardiovascular system and stimulates defenses.

This is because its antibacterial property remains active in the gastrointestinal tract, in addition, it acts as a digestive tonic, cleanses the blood and facilitates the body to purify waste substances, also promotes the response of the immune system and will prevent new episodes of intestinal parasites.

How to apply garlic to deworm dogs and cats

The best way is give it in a natural way, through food, finely chopping garlic and mixing it with our pet's usual food.

Taking into account the recommendation of the Institute of Veterinary Pharmacology and Toxicology of the University of Zurich, the recommended dose of garlic is 4 grams daily, however, the weight of each animal should always be taken into consideration. Likewise, if after the first shot we observe any reaction in the organism of the animal we must go to the veterinarian. Although we apply the recommended doses any living being can have an allergic reaction to garlic, just like people, but these are very specific cases.

To treat intestinal parasites naturally we must mix with the food 1 to 2 cloves of garlic and follow this treatment during a minimum period of 1 week.

Is Garlic Toxic to Dogs?

Garlic, like onions and other plants of the genus Allium, contain TIOSULFATE, a substance that affects red blood cells, producing oxidation at the cellular level. This process, which can take several days or weeks, causes anemia.

The hemolysis, name of the condition associated with garlic poisoning, is usually treated with medication and fluids, in special cases, blood transfusions may be required. Entities and sites such as Pet Poison Helpline, catalog garlic with a medium to moderate toxicity level, highlighting that, in small doses it is harmless, but an intake in large quantities is very toxic.

As indicated by the AKC (American Kennel Club), enter 15 to 30 grams of garlic per Kilo of dog weightwill produce dangerous changes in the health of our hairy. To make it clearer, a clove of garlic can weigh between 3 and 7 grams, so it will take up to 10 cloves of garlic per kilo of weight, so that its red cells begin to show damage.

Can Dogs Eat Garlic? Yes, they can!

Canine nutrition experts, veterinary doctors, owners, even feed brands, are using garlic as a supplement in dog food, for the benefits they bring to pets. Under the premise that the benefit is greater than the risk, more and more people decide to offer garlic to their pets, yes, in controlled doses.

In our dogs, the benefits attributed to garlic They are:

  • It prevents formation of blood clots
  • Lowers cholesterol levels
  • Vasodilator
  • Prevents tumor formation
  • Stimulates the lymphatic system
  • Antibiotic and antiparasitic

There are portals that recommend the consumption of garlic for prevent tick and flea bitesHowever, there is not enough scientific evidence to support these claims.

Dosage of Garlic for Dogs

So far we have only mentioned that, in small and controlled doses, garlic is perfectly safe for our dogs. But what is an appropriate dose?

As indicated by the veterinary doctor Deva Khalsa, garlic can be offered in the following proportions:

  • 10 to 15 pounds of weight - half a clove of garlic
  • From 20 to 40 pounds - 1 clove of garlic
  • from 45 to 70 pounds - 2 cloves of garlic
  • 75 pounds and up - 2 and a half cloves of garlic

These reference amounts are for daily consumption, along with your food, be it homemade food or branded feed. Just mix it before serving and go.

To obtain all the benefits that garlic brings, it is recommended that it be fresh garlic, that is to say, that it still remains with its shell. Garlic It should be finely chopped and should be served and consumed in a time not exceeding 20 minutes. Why should we do this?

The allicin It is a compound with medicinal properties, mainly its antibiotic effects, but this it is obtained by a chemical process, through the catalysis of the enzymes present in garlic. Allicin is very volatile and oxidizes quickly, for this reason garlic must be consumed fresh and in a short period of time, after being chopped, crushed or in pasta.


Today, there is a wide variety of nutritional supplements for dogs that contain garlic. If you are thinking of offering your hairy with these supplements, the use of fresh garlic is not recommended, since the concentrations of thiosulfates are higher and we could cause problems to your health.

Before starting any type of treatment, be it with fresh garlic or supplements, it is important check with your veterinarian, this way they can guide you in the care of your pet. For any warning sign, stop using garlic and contact your veterinarian for proper medical attention.

Although reports of death from garlic poisoning are almost non-existent, the health effects of the dog can be very annoying. Among the main signs and symptoms, you should pay attention to:

  • Excessive salivation
  • Nausea
  • Oral irritation
  • Vomiting and / or diarrhea
  • Lethargy
  • Abdominal pain
  • Accelerated heart rate and breathing
  • Weak> Special cases

It is important to take certain additional precautions, especially when faced with special situations. The fact that certain races, mainly Japanese breeds, have a greater predisposition and sensitivity to garlic is well known. Therefore, its use is not recommended, mainly in Akitas and Shiba Inus.

Similarly, regardless of breed, the use of garlic in pregnant dogs is not recommended, to protect their health and the integrity of puppies. However, it is important to consult with your veterinarian for approval of a safe dose or a supplement with garlic.

Finally, the puppies. Because the puppies' organism is not able to produce new red cells, until after 3 months, the use of garlic is contraindicated. With the approval of your veterinarian you can do it after 6 months, although it may be better entering the 8th month of life.


As we have seen, garlic offers a wide range of health benefits, both for us and for our dogs. More and more experts and entities that recognize these benefits, but also, warn us about the care we should have in doing so.

With several studies waiting to begin, it is still too early to give a final verdict, however, we can be certain that, in adequate minimum quantities, the only thing we can expect are the health benefits of our puppy.

How to deworm a dog with garlic
