Tip: Please Don't Give Garlic To Your Pets

I've responded to questions and tips several times regarding giving garlic to pets for flea control or assorted other reasons, but maybe it will be more helpful if posted as a tip that might reach more folk? Please consider reading up about Heinz-Body anemia before you make the decision to give garlic in any form, or anything in the alliums family for that matter, to a pet. Personally, I wouldn't risk the health of my pet when there are other safe alternatives available. Here are two really good links to begin your homework with:

Tip: Home Flea Treatments

Cat with tongue out.

With two cats who come in and out, I worried about flea treatments.
So I did a lot of reading and saw a recipe in a book and online that recommends that you may add garlic and yeast to your cat's food. They said that it will cause a light scent that repels fleas.

I actually found a powder in my health food store, specifically for pets with garlic and yeast and began adding it to my cat's moist food.

When I brought my cat 'children' to the vet for their regular check up I asked my vet about them and learned something pretty interesting.
Garlic (and onions too, they are the same family) are VERY unhealthy and potentially deadly for cats! Two vets confirmed this for me and yet you can find it in some books and the internet! Take warning!

I had been thinking I was helping them, but was actually potentially hurting them. While I was at it I also asked about flea collars and was told that they are useless on cats as well. So, don't waste your money on flea collars and don't give your pets garlic nor onions. Check with your vet first.
There are "no shortcuts" to preventing flea's (sadly.)

Yes, garlic is safe for dogs, in small amounts over a short period of time. Garlic is widely used as a natural flea and tick repellent and occasionally may even be used as a treatment for heart disease in dogs.

Dogs lack the enzyme needed to break down the chemical thiosulphate in garlic, which can cause gas, vomiting, diarrhea or severe gastrointestinal distress. Large amounts of garlic or garlic given over a prolonged period can result in the formation of Heinz bodies on the surface of red blood cells which are then destroyed by the body.

This results in a severe hemolytic anemia (Yamato, 2005); and there is also an increased risk for the development of blood clotting abnormalities. Always consult with your veterinarian before giving your dog any natural or herbal supplements.

I had a 5 pound Chihuahua and gave her real garlic raw as well as to my other dogs at the time. She liked raw green peppers too. Anyway, take a thing of garlic, pull off a clove and cut it up and give them about a 5th of the clove at a time. It works as dewormer too, which is why I did it in the first place. She's going on 7 years this year and has never had any major health problems.

I've had pets (mostly dogs) my entire life & had flea problems ONE time. For the past 30 years or longer, I've cooked my pets meals & always use fresh garlic 3-4 times a week. And I have NEVER had any trouble with fleas. As far as it being dangerous for dogs, I suppose it could be, but just use common sense, as you would for any other items you feed your pets.

Currently I have 4 "fur children" ages 14, 10, 3 & my new one is 10 months. They are all healthy, happy & free of fleas. I love them very much & would never give them anything that would possibly jeopardize their health. Hope this helps with your garlic decision. Wishing you & your pets all the best.

Garlic Boosting the immune system is crucial to helping your pet defend itself naturally. Adding garlic to a dog's diet is one way  either fresh cloves (for a very small dog, ¼ clove per day; for a large dog, 1 to 2 small cloves a day). I add garlic powder or fresh garlic to their meat/veggie mix when I'm making it.

Some say that garlic powder is useless for this purpose because it has been overprocessed, but I use it more than fresh garlic and it seems to work just as well. Opt for fresh if you can. You can purchase a jar of minced garlic at the store, packed in water or olive oil, or you can make your own. Just mince the cloves, then pour enough olive oil in a glass jar to cover them. Keep in the pantry, not exposed to light.

The olive oil is good for the animal too (contains certain essential fatty acids). There are also preformulated garlic products -- makes a garlic product for dogs that Ive heard great things about.

From Dr. Pitcairns Complete Guide to Natural Health for Dogs and Cats: Garlic helps to eliminate worms, strengthen digestion and beneficially stimulate the digestive tract. Use it to promote intestinal health. It is also indicated for animals that have been on a high meat or fish diet, and those that tend to be overweight or suffer hip pain from arthritis or dysplasia.

Include fresh grated garlic with each meal, use ½ to 3 cloves, depending on the animals size. [p. 87] For your dog, you can purchase minced garlic in olive oil at the grocery store, to save having to mince it yourself. The olive oil is also good for the animal, as it contains certain essential fatty acids. Note that cats should not be fed raw garlic as it can cause a dangerous form of anemia. For more information on adding Kyolic Liquid Aged Garlic Extract (not toxic to cats) to your pet's diet, see

For garlic, add 1/2 minced clove per day to a small dog's meals, for a large dog 1-2 whole minced cloves. Garlic has antibacterial properties as well and is a good immune system enhancer. Digestive enzymes, specifically papaya and pineapple (bromelain) also help fight parasites by irritating and/or dissolving their outer coating, along with aiding digestion. However, if you have a chronic, long standing, and/or severe infestation, it may be best to use a conventional wormer to eradicate the parasites (for many, the damage they cause is worse than the practice of using a chemical to kill them). Then put the animal on one of these natural wormers/preventatives as maintenance.

Apple Cider Vinegar In their book, The Holistic Guide for a Healthy Dog, Wendy Volhard and Kerry Brown, DVM, note that Apples contain a large amount of potassium plus phosphorus, chlorine, sodium, magnesium, calcium, sulfur, iron, fluorine, silicon, and many trace minerals. . . . ACV (apple cider vinegar) is credited with killing bacteria outright. . . . Depending on the size of the dog, add 1/4 teaspoon (toy dogs) to 3 tablespoons (dogs over 50 lbs) total per day to their meals.

Itchy skin is a sign that the skin is too alkaline in nature. Fleas and ticks do not find acidic skin desirable to live on, hence the importance of maintaining a slightly acidic body (for dogs, the normal skin pH range is 6.2-6.5). You can use straight ACV as an after-bath rinse; before going out into the country; and on beginning hot spots. If the skin is already broken, dilute the ACV 1:1 with water so it doesnt sting and spray it onto the skin (test on a small area first, just to be sure it doesnt sting). If the dog has a thick coat, work it into the coat so it reaches the skin.

As an ear rinse, use several drops of the 1:1 dilution weekly to help alleviate chronic ear infections.

These health conditions and others (including sore joints and the beginnings of arthritis), often indicate a potassium deficiency, so ACV is a cheap way to help improve your animals health. If giving ACV orally, purchase a product with the mother (apple fiber particles) in it, not the kind you buy at the grocery store. A good brand is Braggs, which can be found at health food stores. If applying topically, the grocery store products are fine.

There are a lot of remedies on I have found lemon juice sprayed on the ferrets and rubbed in keeps a lot of fleas off of them. I put about a teaspoon of Apple Cider Vinegar per four cups of water for the dogs in the really bad part of flea season. Also we do advantage and one of the dogs does comfortis. Fleas are really bad t his year. Salt put under sheets and on carpet for a few days and then vacuumed up off the carpet kills flea eggs. and vacuum all the time to get the fleas and kill them.

That is a really good idea. Here is the link to the natural remedies for fleas, and dont forget the flea comb~

Garlic Oil to Prevent Fleas

I buy garlic pills (the gel-caps) and poke a hole in one gel-cap with a needle and squeeze the oil into my dogs food about 5 days a week.

Not only is it good for their coat and health, but it does wonder to deter fleas and ticks. Living in the woods, we have a lot of wild animals running through our yard at night, and I have not seen a flea or a tick on my dog.

RE: How Much Garlic Should I Use To Prevent Fleas?

Everything I have found on giving dogs garlic says moderation is the key. I would rather use a little garlic and brewers yeast than stuff like Frontline. Those are pure insecticides. So what would you rather do, put insecticides into your animals bloodstream monthly or give him a bit of garlic which has been used for decades? Dogs use to live for 15-20 years but since these chemical flea treatments have come along I know so many families losing their dogs at 10, 11, and 12 years old due to all kinds of ailments. Personally I believe it's the insecticides. (09/18/2008)

By Mary

RE: How Much Garlic Should I Use To Prevent Fleas?

Be careful giving dogs garlic. It can increase the white blood cells to dangerous levels, I have been told. My vet told me to use Advantage if my dog is in contact with others since she doesn't have fleas, at the moment. Also I have heard that rosemary works well, but must be boiled down. Just the leaves. Then maybe added to their food in moderation.

Personally, I would consult a homeopathic pet care professional if you are not interested in using commercial flea treatments for your pet(s). Always consult a professional when it comes to your pet's health. (09/19/2008)
