Laila from Waxahachie, TXActually, some say it is bad for dogs, and others say it helps with fleas, worms, general health. I know several people who sprinkle garlic powder in their dog's food for fleas/healthy coat. When I did this for my dog, it gave her dandruff. Here are some sites that talk about this in more depth:When onions and garlic are ingested in large or chronic amounts, it results in Heinz body formation and anemia. Cats are more sensitive than dogs to Allium toxiciosis. Clinical signs are generally secondary to the anemia, with resultant weakness, lethargy and pale mucous membranes. Avoid using onion or garlic powder chronically in pet food, and make sure your pet doesn’t ingest large amounts!Using is a natural, inexpensive and safe way to get rid of thefleas biting your dog. When garlic is added to a dog’s diet, it enters the blood stream and the scent and taste of the garlic gets into the skin. Fleas hate the scent and taste of garlic and jump off the dog. An added advantage is that your dog won’t suffer from bad breath due to theingestion of garlic. You can administer garlic to your dog in many ways. You can either add a quarter of a clove of garlic to the dog’s wetfood, or add a garlic tablet to the food. Alternatively, dust your pet’s coat with small amounts of garlic powder or you rub garlic salt into your pet’s coat to rid your pet of fleas.In a scientific study the effects of garlic products, including dehydrated raw garlic powder, dehydrated boiled garlic powder and aged garlic extract, on the gastric mucosa of dogs were determined using three commonly sold preparations, raw capsule garlic powder caused severe mucosal damage, including erosion. Boiled garlic powder also caused inflammation and reddening of the mucosa, whereas aged garlic powder did not cause any undesirable effects. Among the garlic preparations, Aged Garlic Extract could be the most suitable form, particularly for long-term use. Aging in particular may be the most effective method to eliminate the toxic effects of raw garlic. When supplementing pets we recommend using,The small amount of garlic sometimes found in dog treats is unlikely to be harmful to dogs. However, if cats or dogs ingest a tasty pan of sautéed onions, garlic, or leeks, poisoning may result. The ingestion of large numbers of garlic pills or powder may also cause poisoning. Garlic was once thought of as a “home remedy” for flea infestations; however, it has been shown to be ineffective and is not recommended by Pet Poison Helpline.Raw garlic fed daily may be hard on the GI tract and cause digestive upset or diarrhea. This means your animal can’t really eat enough to get true therapeutic dosages. Dehydrated powder or cooked garlic has gone through a heat process that destroys much of its benefits, so the best form to use is a purified extract, often fed in a gel cap. This form can easily get into the intestines in concentrated amounts, benefiting the animal without digestive upset. Dosage is approximately 1/2 capsule for a small dog and up to 2 capsules for a large dog.
