Natural flea and tick pet med alternative: brewer’s yeast

Brewer's yeast may help repel fleas

While there are of course many effective topical flea and tick medicines that work wonderfully in most dogs, such as K9 Advantix II, Frontline Plus, and Revolution, there is the occasional pet that will have a rare topical or systemic reaction to any of these medications, and so many clients are often asking about natural flea and tick alternatives, especially as the flea season bears down on most of the country.

While the efficacy of many of these products can vary, I have indeed found that adding nutritional supplements such as Brewers Yeast and garlic to the diet can often help repel fleas for many pets. Chock full of vitamin B, Zinc, and biotin, Brewers Yeast is simply wonderful for skin and coat health, including helping with unwanted shedding in many pets. Along with garlic in these tablets, many clients do report a reduction in flea infestations in their pets. They can safely be added to most pets’ diets and have no side effects in my experience and opinion.

  1. Thank you for your helpful suggestions.
    I have 2 GSD designer dogs that I give brewers yeast and garlic to. The largest one has no problem with any kind of garlic but the smaller one gets an upset stomach unless the garlic has been slightly cooked and eaten in very small amounts.
    I hope this helps someone who has a dog with a sensitive stomach to be able to improve the dog’s health & happiness by it eating these two excellent foods.
    Sincerely,
    Daniel Z

    HI Daniel: As in people, every pet is an individual and individuals can have allergic reactions to any supplement, even natural ones on occasion. Thanks for sharing. I am sure others will benefit from your posting.

    Brewers yeast and garlic will work on some pets while not always on others. Every animal is an individual with their own susceptibilities. It is always great when one can try natural approaches, whether through diet or topically.

    If given in too large a quantiy, garlic can cause issues. Check that out by googling garlic in cats. I dont have exact amount by memory, but have not seen problem when added to typically amounts added to cat meals.

  5. These suggestions are wonderful. Thanks so much. But is there any harm in giving garlic to dogs. May be as part of their food. Since garlic has proved to be of much health benefits to human, I think it can be even to pets.

    Only if garlic is given in too much quantity. However at small 1/2 to clove amounts it should not be a problem.

  7. Can I give garlic to a dog to help yeast in their system?

    I dont see a problem with small amounts of garlic

  9. My dog seems to react very badly to Advantix, after applied she runs around like something is chasing her. She hides under the table and is very upset. It is almost 24 hours since I applied it to 3 locations on her back. |Any suggestions of what I should do to releave whatever her issue is, and is there a product that is good for ticks and fleas that can maybe be taken orally

    You can try oral comfortis or topical revolution. Give your dog one dose of homeopathic nux vomica in 30c potency, which may help with allergic reaction to advantix and bathe her to remove any residue. See vet if signs persist or worsen.
