Can Dogs Eat Garlic? Is Garlic Safe For Dogs?

Can dogs eat garlic?

This guide is a detailed answer to this question.

I am going to be covering everything about the safety of feeding garlic to dogs and also shade more light on the dangers of doing so.

So without further ado, let`s dive in.

Just like onions, garlic also belong to the genus Allium family. The garlic plant is native to Central Asia and Northeastern Iran where it is still widely grown.

Garlic has throughout the years gained a reputation as a great seasoning with a lot of health benefits for humans.

But is garlic safe to dogs just as it is to humans?

Are Dogs Allergic To Garlic?

Are dogs allergic to garlic and is it safe for them to eat the herb?

Here is the short answer…

Yes. Dogs are allergic to garlic and this because garlic contains a toxin called n-Propyl disulfide which is safe for humans to eat but is extremely dangerous for dogs to consume.

In the next sections I am going to be fully explaining the toxicity of garlic and effects of N-propyl disulfide to dogs.

Can Dogs Eat Garlic? Is Garlic Safe And Good For Dogs?

Dogs cannot eat garlic and as mentioned earlier, this is because garlic contains a toxin called n-Propyl disulfide which is extremely dangerous for consumption by dogs and other group of animals.

n-Propyl disulfide is completely safe for humans but it reacts differently when in ingested by a dog.

The toxin combines with oxygen molecules inside the red blood cells of the dog`s blood stream and reduces the ability of the blood cells to carry sufficient oxygen for the body`s metabolism.

The body is then tricked to consider the red blood cells as foreign bodies and as part of its defence mechanism it will then destroy the cells.

Once the red blood cells are destroyed in a process called hemolysis they become deformed and the result is a condition known as hemolytic anemia.

How Much Garlic Is Toxic To Dogs?

Garlic is a herb that is related to onions, leaks and chives so the effects of all these food plants are the same when consumed by dogs.

Onions are considered to be more toxic than garlic and should be avoided completely. However, when used in moderation, garlic can be safe for dogs to eat.

In 1981, Malik and Siddiqui studied the hypotensive effect of freeze-dried garlic sap in dogs as they attempted to figure out the amount of garlic that would cause hemolytic anemia in the four-legged animal.

According to a report by the National Center Of Biotechnology Information

Garlic extract was administered intragastrically (1.25 ml/kg of b.wt. (5 g of whole garlic/kg) once a day for 7 days). Compared with initial values, erythrocyte count, haematocrit and hemoglobin concentration decreased to a minimum value on days 9 to 11. Heinz body formation, an increase in erythrocyte-reduced glutathione concentration, and eccentrocytes were also detected, however, no dog developed hemolytic anemia.

These studies have found that it takes about 15 to 30 grams for garlic to cause harmful effects to dogs.

What Happens If A Dog Eats Garlic?

The ultimate effect of garlic poisoning in dogs is the damage of red blood cells which causes hemolytic anemia but before that happens there are some initial symptoms that occur immediately after garlic consumption.

The first symptoms are usually:

  • vomiting
  • diarrhea
  • abdominal pain
  • loss of appetite
  • depression
  • dehydration

After a few days the signs and symptoms associated with the loss of red blood cells will begin to show.The second stage of symptoms are:

  • pale mucous membranes
  • rapid respiratory rate
  • difficulty to breath
  • lethargy
  • dark colored urine (usually reddish or brown)
  • jaundice
  • weakness
  • rapid heart rate

Treatments Of Garlic Toxicity To Dogs

There is no antidote to treat the effects of garlic toxicity in dogs so the first thing to do is to induce vomiting in order to get rid of any garlic inside the dog`s body before it causes any damage.

If your dog ingests a lot of garlic we strongly recommend that you call the pet poison helpline (855) 764–7661 or visit your nearest vet for professional medical advice.

Can Garlic Kill Your Dog

Hemolytic anemia caused by garlic poisoning in dogs is a condition whereby red blood cells are destroyed faster than they are made and this reduces the amount of oxygen received by other body cells for metabolism.

If medical attention is not received sooner, the effects of garlic toxicity can definitely kill your dog.

Immediately seek medical attention once you are aware that your dog ingested a lot of garlic or even if you suspect that they might have taken a small bite.
