2 Recipes for Flea Terminator Dog Treats

I absolutely HATE dealing with fleas on my dogs. They make my dogs itch and scratch and they can carry heart worm – which can and does kill dogs. That’s why I look for solutions like these homemade flea treats for dogs in order to prevent flea infestations in the first place.

Why Brewers Yeast for Dogs’ Fleas Works to Help Prevent Flea Infestations.

Fleas don’t like dried brewer’s yeast, and they especially don’t like garlic. Garlic also really helps as a flea repellent.

Now I know that garlic is often listed as poisonous to dogs, but that is only in MASSIVE quantities.

The small amount of garlic powder in these dog treats IS safe for dogs, and brewer’s yeast and garlic for dogs works very well to help prevent flea infestations from happening in the first place.

I have a whole section at the end of this article about garlic powder in dog treats. Make sure you check that out if you have any questions about the safety of garlic.

If you want a brewers yeast recipe that doesn’t contain garlic, make sure to check out the second recipe on this page – Coconut Oil and Brewers Yeast Dog Treats.

Side note: if your dog already has fleas, you can help your dog out with a simple trick.

Put a 1/2 teaspoon of cider vinegar in their water dish.

Our old water dish held about one cup, but the general idea is about 3 tablespoons to a gallon of water.

The cider vinegar makes dogs not taste so good and the fleas will often look elsewhere for solutions.

But to stop your dog from getting fleas at all, you can try these treats.  The garlic changes your dog’s smell enough to make her unappealing to fleas.

Recipe 1: Brewers Yeast and Garlic Dog Treats


  • 3 cubes beef bouillon
  • 1 1/2 cups boiling water
  • 2 cups whole wheat flour
  • 1 cup cornmeal
  • 2/3 cup brewers’ yeast
  • 2 tablespoons garlic powder
  • 2 egg yolks


  1. Preheat the oven to 375 degrees F (190 degrees C). Dissolve beef bouillon cubes in boiling water, and set aside. Grease cookie sheets.
  2. In a large bowl, stir together the whole wheat flour, corn meal, brewers yeast, and garlic powder. Add the yolks, then gradually pour in the bouillon water while stirring. Mix thoroughly to form a firm dough. On a floured surface, roll the dough out to 1/4 inch thickness. Cut into desired shapes using cookie cutters. Place cookies one inch apart onto cookie sheets.
  3. Bake for 20 minutes in the preheated oven, then turn the oven off, and leave the cookies inside for at least 3 hours or overnight to harden. Store in an airtight container at room temperature.


You can substitute chicken bouillon for the beef here.  Go with whichever flavor your dog prefers.

Recipe 2: Coconut Oil and Brewers Yeast Dog Treats

This is a crazy simple recipe with only two ingredients and no baking at all. It’s a great way to use brewers yeast and coconut oil for fleas.


-1 and 1/8 cups Organic Coconut Oil melted
-1/2 cup Brewers Yeast slightly rounded
-2 silicone mold pans, I like the ones with pawprints


  • Combine melted coconut oil and brewers yeast together in your blender. Blend for roughly 10 seconds until smooth.
  • Transfer blended mixture into a plastic condiment bottle (trim tip to 1/4 inch opening) and use to fill 2 – small paw print silicone pans.
  • Chill in the refrigerator or freezer until set & solid.
  • Remove from the pan and store in refrigerator or freezer for up to 6 months.

When making this recipe I like to use these silicone molds that you can find on Amazon. (paid link)

Garlic Powder in Dog Treats – Is it Safe?

A word about garlic.

Most of you know from other posts and common information on the web that garlic is poisonous to dogs. But in this recipe. I’m telling you to use garlic. Here’s why.

Garlic and onions are part of the lily family.

Most of us realize that lilies are toxic. Most of the toxin is in the bulb of the plant. And since we eat the bulb of the plant for both garlic and onions, there is a lot of concern about dogs and cats getting hold of these plants.

BUT… small quantities of garlic WON’T hurt your dog.

Honestly, the amount of garlic that a dog would need to consume to be harmed is extremely large.

For a 50 pound dog, he would need to eat around 25 large whole wall garlic cloves. That’s a lot of garlic.

I don’t know anyone who keeps that much garlic on hand, let alone accessible to their dog.

So, while I’m not saying it’s okay to let Fido get a hold of lots of garlic, or that you should not be concerned if your dog gets too much garlic, it is safe to use the small amount of garlic that is used in this recipe.

If you would like to know more about this, you can click this link to a site that talks specifically about the impact garlic has on dogs.

Once you’ve gotten the fleas taken care of it’s possible that your dog will still have itchy skin from the flea bites, to soothe dog skin try my homemade dog anti-itch spray.

Question. Is that to much sodium in the bouillon? Just a question as I'm unsure.

Best to put the silicone trays on a cookie sheet before you fill them because they will ooze all over when you try to lift them full.
