Yeast.
Having a pet consume more vitamins and possibly like yeast tablets are some of the advantages of using brewer’s yeast for fleas. Brewer’s yeast tablets rarely contain yeast alone; Dozens of vitamins and herbs are sometimes included to benefit the animal’s coat or help prevent fleas. Also, some pets love the taste of the tablets, so treating a pet for fleas is no longer a problem. Brewer’s yeast does have some drawbacks, including that it hasn’t been shown to repel fleas and the possibility of causing gas.
A flea.
Flea brewer’s yeast usually comes in tablet form fortified with other vitamins. Even if the flea treatment is not effective, the dog can benefit from the other vitamins that he has consumed. Also, unlike most other flea prevention methods, brewer’s yeast is not known to cause a reaction in dogs. Therefore, dogs with allergies and sensitivities may benefit from using yeast instead of potentially harmful chemicals found in some flea medications.
Some cats and dogs find brewer’s yeast tablets delicious, so they are happy to take them.
Using brewer’s yeast for fleas may be less bothersome because some dogs and cats like to eat brewer’s yeast tablets. They see them as a treat, unlike the liquid that is applied directly to the skin. Additionally, dogs can be trained to know that a treat follows brewer’s yeast, even if they don’t like yeast. Cats are a bit difficult to train, but not impossible.
Giving a dog the tablet form of brewer’s yeast may be ineffective.
Studies show that the use of brewer’s yeast for fleas is ineffective when given to dogs in tablet form. One study fed brewer’s yeast to 40 dogs and elicited and observed unfed fleas on the dogs over the course of seven weeks. The researchers saw no indication that brewer’s yeast could repel fleas. It could be another ingredient in most flea repellant brewer’s yeast tablets, or dog owners could be experiencing a placebo effect.
Bloat in dogs can be a fatal condition; in fact, it is estimated that up to 60% of dogs die from this disease, even with treatment. It is caused by an excessive amount of gas that accumulates in the stomach. Some foods and habits can cause gas and increase a dog’s risk of developing bloating. In general, experts advise against giving brewer’s yeast to dogs that are already at risk of bloat. It’s important to talk to a veterinarian about the dog’s diet and how to prevent bloat, especially if one or more of the dog’s family members have died from the disease.
