Risk Factors For A Yeast Allergy

Yeast Or Allergy – What Is Causing Your Dog To Itch?

Anyone can develop a yeast allergy, but certain individuals are more likely to than others.

One of the most common risk factors for developing a yeast overgrowth or allergy is a weakened immune system. People with diabetes mellitus are also at a higher risk.

People with a family history of a yeast allergy are at increased risk. And if you have a food allergy, there is an increased likelihood that youre also allergic to something else.

Symptoms Of Brewers Yeast Allergies In Dogs

Canine food allergies can develop at any age, but the majority of dogs who acquire food allergies are three years old or older. Skin reactions are often located on or around the face, groin, under the front legs, or between the toes.

  • Bald patches
  • Poor growth in young dogs
  • Skin infections


Food allergy

– An allergy to food is a response by the white blood cells in the bodys immune system to protect itself against a protein that it views as a threat. An allergic reaction doesnt happen upon initial exposure to an allergen as it takes multiple exposures to alert the immune system. Some foods, such as beef, chicken, dairy, and eggs are prone to cause allergies in dogs, although any food can become an allergen.

Food intolerance

– Food intolerance has no immune involvement. It can have several core triggers, including missing enzymes in the animals system, toxins, and a natural occurrence of histamine present in the food itself, usually due to improper storage. Gastrointestinal symptoms, such as vomiting and abdominal pain are more common with food intolerance than with allergies alone. Additional symptoms, such as gurgling sounds from the digestive system and a change in the consistency or color of the stools are common with instances of food intolerance.

Causes & Symptoms Of Ear Infections In Dogs

Your dogs ears naturally have yeast and bacteria in them, but ear infections occur when the ear becomes moist and inflamed with increased wax and discharge. This allows the yeast and bacteria to multiple and overwhelms the immune systems ability to control the infection. If you notice your dog scratching their ears or shaking their head more often than usual, dragging the side of their face along the carpet or furniture, smell a bad odor from the ear, or see redness on their inner ear flap or in their ear canal, they could have an ear infection.

When To See A Doctor

Yeast allergy may be a sign of a weak immune system or may be associated with other diseases like diabetes. If allergy symptoms occur repeatedly or recur often and are associated with other symptoms, it is best to consult a doctor for adequate diagnosis and medical treatment. The underlying problem, such as diabetes or immune disorder must be treated in order to improve allergy symptoms.

People who suffer from recurring symptoms of diarrhea, abnormal vaginal discharge, sinusitis, chronic cough, sore throat, nervousness, or insomnia should consult their doctor for yeast overgrowth. Skin conditions often manifest as unexplained rash which does not go away with conventional treatment. These indicate that one needs to see a doctor for proper treatment.

How Does Yeast Affect The Skin Of A Dog

Home Remedy for Dog Skin Yeast Infection

How Yeast Affects Your Dog. Well, yeast is a fungus that likes to grow in moist areas. Yeast on a dog typically affects a dogs skin resulting in an itchy dog. Malassezia is the most common type found on a dogs skin and is usually found on the paws, ear canals, armpits, jowls, anal area and any skin folds that your pooch may have.

Are There Home Remedies For Yeast Infections In Dogs

The only home remedy for yeast infections in dogs that has any scientific data to support it is a vinegar rinse. A vinegar rinse is able to help change the pH of the skin to make it less desirable for yeast. The proper dilution is essential to avoid irritation. You should only attempt this after speaking with your veterinarian for guidance and direction.

Health Risks Associated With Nutritional Yeast

In some cases, you may find it best to avoid nutritional yeast altogether. If you eat yeast, youll want to do so in moderation.

  • Nutritional yeast is high in fiber. If you eat too much fiber, and your body isnt used to it, you may get cramps, discomfort, or dehydration.33
  • This yeast contains a hormone called tyramine. Tyramine might cause headaches, as well as high blood pressure.34,35
  • Nutritional yeast also contains niacin. Consuming high amounts of niacin could cause facial flushing or, in extreme cases, liver damage.36-38
  • Nutritional yeast can trigger allergies or intolerances. A yeast allergy can be difficult to diagnose because the symptoms are similar to other, more common conditions.39,40
  • Yeast, including nutritional yeast, naturally contains monosodium glutamate, or MSG. If you are sensitive to MSG, youll need to avoid foods that are made with yeast.41
  • Some brands of nutritional yeast have detectable amounts of lead. The level is low, but pregnant women should still be careful about eating nutritional yeast.42

Nutritional yeast can be a beneficial addition to your diet, however, you should be aware of side effects. Be especially careful if you have allergies, or if youre pregnant. Again, if you are concerned about nutritional yeast, or youre making any dietary changes, talk to your doctor first.

Extent Of Elimination Of Yeast & Mould Required

The length to which a person must go to avoid all forms of yeast and moulds in the diet depends on their level of sensitivity.

After following a yeast and mould free diet for a period of about four weeks, an incremental dose challenge should be carried out to determine whether some yeast derivative could be taken with impunity.

An example would be malt as a flavouring. It is possible that moderately allergic people will exhibit no adverse effects. Malt is a commonly used flavouring in many baked goods, breakfast cereals, and commercially prepared foods, and including malt as an ingredient would allow beneficial liberalization of the diet.

Nutritional Yeast: Its Not Like Other Yeasts

Does A Yeast Infection Cause An Allergic Response? | Ask Eric Bakker

You might know that yeast is used in breads and beers. If youre unlucky, you may have gotten an infection from yeast in the past. Bread yeast, beer yeast, and infection-causing yeast are different kinds of yeast, but they all belong to the same family.

  • Yeast cells are classified as fungi. There are many kinds of yeast, but the three main types that you can eat all belong to the same species. There are other kinds of edible yeast, but they arent as common on grocery store shelves.1
  • The three main kinds of yeast you can eat are nutritional yeast, bakers yeast, and brewers yeast. These three yeasts are used as ingredients in many foods to add flavor or nutrition. Bakers yeast also makes bread rise.1
  • Nutritional yeast is a deactivated yeast, meaning the yeast is cooked, so the fungi are dead by the time you eat it. Nutritional yeast has a nutty or cheesy flavor. Vegans use nutritional yeast seasoning because it has a savory flavor and great health benefits.3,4
  • Brewers yeast is used to brew alcohol. It is still alive at the start of the brewing process. After it dies, you can eat it, just like nutritional yeast. In its deactivated form, it tastes bitter. This yeast has gluten, unlike nutritional or bakers yeast, which are gluten-free.5
  • Bakers yeast is used for baking bread and in other baked goods. The yeast is alive when it goes into the dough, but the cooking process kills it. You can find this yeast in bread and cheese.6

Probiotics Are Likely Helpful In Fighting Yeast Infections

The candida diet also recommends ingesting probiotics or yogurt containing live cultures of the popular “friendly” bacteria, Lactobacillus acidophilus.

Probiotics are also a popular choice for curing or preventing yeast infections with natural products or home remedies .

The idea is that that normally, certain bacteria live in the digestive tract, on the skin, and elsewhere on the body, where they help with digestion and other bodily functions. Therefore, probiotics can help restore the body’s normal bacterial balance, preventing Candida yeast from growing out of control and causing an infection. .

While trying probiotics poses little harm, strong scientific evidence supporting the use of probiotics for yeast infections is lacking.

In 2017, a review published in the Cochrane Database of Systematic Reviews found that there’s only low- to very low-quality evidence showing that probiotics can help with yeast infections.

What Is The Risk Of Infection With Nutritional Yeast In Diet

If youve ever had a yeast infection, you know how unpleasant it can be.

The good news is, eating nutritional yeast doesnt cause infections.
  • A yeast strain called candida causes infections. This is a different strain from what is used to make nutritional yeast and other yeasts that you eat. The most common strain that leads to yeast infection is Candida albicans.29
  • Candida naturally lives in your digestive tract. Infections can happen when your body becomes overrun with this type of yeast.30
  • Again, candida yeast is not nutritional yeast. Nutritional yeast almost never causes candida overgrowth.31

Although most allergy-related yeast infections are on the skin or in the ears, systemic infections by the Candida yeast are also possible.

  • Bladder infections


Candida albicans

– Candida albicans is a yeast that generally lives in the digestive tract. The overgrowth of this kind of yeast can cause a disease known as candidiasis in dogs and humans. Infections by this yeast can become systemic, which untreated may lead to infections of the urinary tract, swelling of the membranes protecting the internal organs, and may even compromise the immune system.

Malassezia pachydermatis

– This yeast is often found on the skin of healthy animals, but it can flourish to excess and release destructive enzymes on host cell membranes, which can result in uncomfortable, malodorous rashes and ear infections. Although there are many types of Malassezia yeast that attack humans, M. pachydermatis is the most likely variety to act as an opportunistic pathogen on canines.

Recovery And Management Of Yeast Infection In Dogs

Pin on Women

Recovery depends on the severity of the infection. If its mild and caught in the early stages, it can clear up in a few days. If its a severe infection, it can take up to a few weeks to completely heal.

Managing a yeast infection requires continuous monitoring of your dogs immune system. Frequent baths with antifungal shampoo and sprays will help soothe the skin, although you should check with your veterinarian before beginning any at-home treatments.

Causes Of Yeast Infection Due To Allergies In Dogs

Allergies have an adverse effect on the immune system and may leave some dogs more susceptible to yeast infections. One of the symptoms of allergies, particularly in canines, is itchy and inflamed skin. Dogs often itch this skin, leaving lesions or minuscule scratches which can become ideal breeding grounds for the yeast to grow in. Certain breeds of dog may be slightly more vulnerable to yeast overgrowth. Breeds that show a predisposition to developing yeast infections can include:

  • Australian Terrier

What Is A Dog Ear Yeast Infection

This type of yeast infection affects the visible part of your dogs ear. Inflammation in the outer flap of your dogs ear is called otitis externa.

A dog ear yeast infection may be mistaken for allergies. But its often caused by yeast. It could be candida, the most common type of yeast but it might also be malassezia, a different fungus. Yeast can smell musty a bit like an old shoe. Your dogs itching will be intense, and there may be a brown or black discharge .

So What Is A Yeast Infection In Dogs

Malassezia pachydermatis is a yeast/fungus that likes to grow in moist areas of a dog. It’s generally found on the paws, ear canals, armpits, jowls, anal area, and any skin folds that your pooch may have.

Finding small amounts of yeast on dogs is normal, it only becomes a problem when yeast grows out of control. When this happens its known as Malassezia Dermatitis or a yeast infection.

Yeast may also be a problem for dogs if they become hypersensitive to Malassezia. In other words, they become allergic to the fungus on their body.

Dogs that are allergic to yeast will react to the smallest amount of yeast. So, for them, it doesn’t need to be out of control at all.

My dog, Ava, is allergic to yeast. I discovered this through skin allergy testing after many years of Ava’s itchy ears. This means that even a small amount of yeast will cause her to itch and scratch like crazy.

So, to reiterate. All dogs have yeast on their skin, but it doesn’t usually bother them unless it grows out of control. OR, if the dog is allergic to the fungus. In that case, it’s known as “hypersensitivity reaction to Malassezia.”

You can find more studies on this here. But I wanted to share this with you as it took me four years to figure out it was this that Ava suffered from.

So What About The Yeast

Can A Yeast Infection Cause Swollen Lymph Nodes? | Ask Eric Bakker

During your pets examination the vet will check for any evidence of a concurrent skin infection. Skin infections can be caused by bacteria or a fungi/yeast known as Malassezia. Malassezia is a type of yeast that is commonly found on the skin of normal healthy dogs .

However, in dogs with damaged skin, a reduced immune system or an underlying allergy, this Malassezia is able to cause skin disease. They could have a reduced immune system secondary to an illness such as diabetes, cancer, an underactive thyroid or due to long term skin allergies. As the skins resistance to the yeast lowers, the yeast can multiply and spread. This results in red itchy yeasty smelling skin. This type of yeast infection is common in Basset Hounds and West Highland White Terriers.

Its not that the dog is allergic to yeast. Its that theyre allergic to something else which has allowed the yeasts to overgrow.

How Are These Diseases Treated

Malassezia yeast infections can be treated with special medical shampoos or creams, or in more severe cases a course of tablets. Its important to note that because Malassezia infections occur secondary to other problems, in order to resolve the problem the underlying cause will need to be successfully managed.

This will involve identifying other conditions if your pet is showing other clinical signs seen with this disease. They can be picked up via a blood test and then managed appropriately.

In the case of skin allergies, there are a variety of treatment options available. Some treatments work by suppressing the immune system to reduce the inflammation or itch . Others involve training the immune system to react differently . As with any medicines, each option comes with its pros, cons, and costs. This is something your vet can discuss with you to find the best option for you and your pet.

Symptoms Of Yeast Allergy

It may be manifested early as digestive problems, such as:

  • Bloating
  • Indigestion
  • Heartburn

Some people develop a leaky gut syndrome, where the yeast is able to penetrate through the intestinal walls and travel through the bloodstream, causing generalized symptoms, such as:

  • Fatigue
  • Joint pains
  • Muscle pains

Yeast infection can affect the mouth, causing a condition called oral thrush, and this may be seen as a white spots in the mouth and a white tongue.

Yeast can also affect the skin, causing skin rashes, such as those found in diaper rash. Other forms of fungal skin infection include dandruff, athlete’s foot, and jock itch. These are characterized by itchiness, redness, and inflammation.

Other problems may also be associated with yeast overgrowth, such as ear problems, bladder infection, infertility, and psoriasis. Vaginal yeast infection is also a common type of yeast infection and manifests as vaginal itchiness and abnormal vaginal discharge.

The Best Diet For Dogs With Yeast Infections

The best food for dogs with yeast infections is a frozen low-carbohydrate raw novel-protein diet. Some meat proteins, like chicken, turkey, duck and beef, are potential allergens for dogs. Diets high in grains can cause inflammation and skin problems in dogs. Dairy products, like milks or yogurts, are very high in sugars and should be avoided. Potatoes and sweet potatoes are starchy vegetables and are not recommended for dogs with yeast. Green vegetables such as zucchini or green beans are excellent additions to your dogs meals. They also make great treats.

Signs And Symptoms Of Yeast Infections In Dogs

How to Treat Ear Yeast Infections in Dogs

You can usually tell if your dog has a yeast infection by watching for these signs and symptoms.

First, the paws. Dogs sweat from their paws, so it’s the paws that contain a moist wet environment that yeast loves. You can usually tell if a dog has yeast on their paws by the pungent smell…it’s a bit like Fritos.

They’ll also be licking and chewing at their paws a lot. Their saliva discolors the fur making it a rust color. You’ll notice this on any areas that they lick, including the hair between their toes.

The ears will also be an area that you can easily detect yeast.

Dogs with yeast in their ears will be itching and scratching at their ears.

They’ll also be shaking their heads a lot. But the biggest clue is you should be able to see yeast in the ears.
