Allergy and intolerance to Brewer’s yeast in dogs and cats

Updated: Apr 28

While Brewer’s yeast is known as a great source of vitamin B, it is widely used as a supplement for dogs and cats to improve skin and coat health, blood sugar regulation, as an insect repellent and calming agent. However, Brewer’s yeast is a by-product of the beer brewing process and can be toxic to dogs and cats, causing intolerance or an allergic reaction to an unwelcome protein found in the yeast. Allergy and intolerance to Brewer’s yeast are relatively common in dogs and cats.

Along with intolerance to Brewer’s yeast that may cause an unpleasant sensation, pain, and discomfort, yeast allergy can trigger a severe reaction. Signs and symptoms of allergy in your pets can vary and may affect skin, ears, digestive system, or even the reproductive system. The skin reaction is seen through itching, irritation, scratching, and constant chewing of paws that can lead to secondary skin infections. Dogs and cats with allergies to Brewer’s yeast can also suffer from chronic ear infections. Digestive problems include diarrhea, nausea, intestinal spasm, and blot, which can be a life-threatening medical emergency. Symptoms of the blot in dogs and cats after ingesting Brewer’s yeast are stomach pain, enlarged abdomen, retching, and salivation.

Brewer’s yeast is an ingredient that has no taste and may be found in a variety of food and supplements that your dogs and cats ingest every day. Yeast is found in lots of animal food and ingredients that might not be expected. Some of these foods include processed and cured meats, smoked and dried meat, poultry and fish, cheese, baked goods, some grains, peanuts, and peanut products, as well as additives like hydrolyzed and textured vegetable proteins and yeast extract.

Brewer’s yeast is also included in some glucosamine supplements for dogs and other health supplements. As it was mentioned above Brewer’s yeast supplement is commonly used to improve some health conditions in dogs and cats.

If you have any suspicion that your pet may have an allergy or intolerance to Brewer’s yeast, you must discuss the problem with a veterinarian that will order a blood allergy or food intolerance test to determine the offensive substance. If the results of the test show that your pet has an allergy or intolerance to Brewer’s yeast which is common for dogs and cats, you must eliminate all food ingredients that can be potentially harmful. Always carefully read supplement labels, as taking this supplement can completely defeat the purpose for your pet.
