Dog Yeast Infection
Fungal
and Yeast Infections in Dogs
Skin diseases
are common in dogs, and many such diseases fall into one of three categories:
Fungal infections, yeast infections or fungus/yeast infections. These
are almost never fatal, but they are sometimes chronic - so it's wise
to keep an eye out for symptoms that may indicate your dog is infected.
Candida Albicans
is a fungus/yeast and a common microorganism that lives in the gut of
a humans and dogs. But when there is an "overgrowth" of this fungus/yeast
in the gut, it is called a Systemic Yeast Infection, and it affects the
health and well-being of the whole animal or human.
When the
pH balance of the gut is out of balance, and beneficial bacteria in the
gut have been destroyed, this insidious fungus and pathogenic bacteria
can take over and the negative results are very detrimental to our health
and well-being. One of those by products of a pH imbalance in the gut
is bloat/torsion.
What causes
the pH balance of the gut to be out of balance and cause fungus/yeast
overgrowth?
- Overuse
of antibiotics - killing off good bacteria in the gut
- Poor Nutrition (inadequate protein, too many carbohydrates, no probiotics,
digestive enzymes, dietary enzymes, unusable minerals)
- Over vaccinations (i.e. allergies, thyroid problems)
- Thyroid problems = metabolic problems (the body's electrical system)
- Hormone stress (seasons, whelping, lactation, vaccines)
- Stress (environmental, genetic, physical, emotional etc.)
- Anxiousness (males when bitches are in seasons)
- High strung hyperactive dogs
- Death/loss
- Change in environment or weather related (heat or cold)
- Change in home or home environment
- Boarding
- Inbreeding -compromised immune system
- Illness which compromises the immune system
- Sensitivity to stimulus (light, sounds, movements)
- Travel (showing)
- Medications
- Flea preparations
- Heartworm medications
The result
of this yeast/fungus overgrowth manifests itself in external and internal
expressions of disease. Based on clinical and research studies, Candida
overgrowth in the intestines will create what has been called as "leaky
gut" syndrome. Toxins and food allergens may pass through this membrane
and go to other parts of the body, making him feel generally sick all
over. Since antibiotics don't affect Candida yeast/fungus, they keep on
multiplying and making more yeast, which in turn, puts out more toxins
and weakens the immune system. It is a vicious cycle.
Some examples
of "external" expression of a systemic yeast infection are:
Skin Irritation
- Itchy skin or feet
- Licking paws, genital or vaginal area
- Itchy mouth, throat, face
- Rubbing nose
Redness,
Inflammation and Odor
- Underarms, Folds of Skin
- Inner Thighs, Between Toes, Lips
- Joint pain
Reoccurring
Secondary Bacterial Infections
- Ears
- Bladder
- Skin or Feet
- Sensitivity to light, sound, movement
You can see
by this list of symptoms the animal is often misdiagnosed as having a
food or contact allergy, or only a bacterial infection, when in fact the
origin of the disease is yeast/fungus overgrowth.
Some examples
of "internal" expression of a systemic yeast infection are:
1. Gastrointestinal tract problems
2. Gas/bloating - Bloat/torsion
3. Lethargy
4. Depression
5. Fatigue
6. Arthritis
7. Suppressed immune system
8. Inadequate absorption of nutrients
Other facts
about Candida overgrowth - Systemic Yeast Infections:
Systemic yeast infections (fungus) are extremely difficult to detect and
kill.
When pH balance
of the gut is out of balance, an environment is ripe for pathogenic bacteria
and fungus to multiply at an alarming rate.
The by-products
of bacteria and fungus produce "toxins." These can result in systemic
disease, as well as bloat, stomach gas and foam.
Control Fungus Internally:
Feed a high
quality based diet.
Use a metabolic
enzyme (Nzymes) to detoxify the body.
Use probiotics/digestive
and dietary enzymes to keep the pH balance of the stomach in proper balance.
This in turn helps prevent yeast overgrowth.
Use raw apple
cider vinegar or lemon juice - 2 teaspoons per day on food or in water,
to help keep the pH balance where it should be in the gut and make an
environment, which is not conducive to yeast proliferation.
Use Oxy-drops
in drinking water or on food, to keep fungus and pathogenic bacteria overgrowth
in check.
If you using
a combination of Oxy-Drops and Raw Apple Cider Vinegar, vets usually suggest
using the Apple Cider Vinegar in the water, and the Oxy-Drops diluted
solution (1 drop per 20 lb.) mixed with some water and added on the food
so they don't cancel out each others benefits. One is alkaline the other
acidic so they can't be put in their water or food at the same time.
Control
Fungus Externally:
1. Bathe
in sulfur-based or medicated shampoo
2. Prepare a 50/50 mixture of Apple Cider Vinegar & Water
3. Rinse or wipe affected areas with 50/50 mixture daily. Note: Do not
use Apple cider mixture on open lesions
4. Prepare a 2% solution of Oxy-Drops (1 teaspoon + 1 cup of distilled
water). Use this to spray or wipe skin, ears, and feet with to prevent
secondary bacterial infection.
5. For ears - your vet can recommend the appropriate medication.
Always consult
with your veterinarian for his recommendations.
Ringworm:
Ringworm (caused by the fungi Microsporum and Trichophyton) is the primary
fungal infection that troubles dogs. Such fungi live in dead skin tissues,
nails, and hairs - particularly, but not exclusively, among young dogs.
Symptoms include:
Hair loss,
usually in circular patches
Hair loss patches that may have a crusty, dry look
Hair loss on the head and legs
Scratching of the patchy areas
If your dog
develops these symptoms, take him to his veterinarian right away. If your
vet suspects ringworm, he will probably run a Wood's Lamp Test (using
an ultraviolet light), or take a fungal culture.
Typically,
treatment includes: Trimming or shaving the hair around affected areas,
using fungicidal shampoos for bathing the dog, applying a topical antifungal
medication, and lime sulphur dips
Ringworm
is quite contagious to both animals and humans, with children being especially
vulnerable. Dogs with ringworm must be kept away from children and other
pets until the infection is gone. (This may two or three months, or longer.)
Adults should wash their hands well after handling a dog with ringworm.
Blastomycosis:
Blastomycosis is a fungal disease usually found in both dogs and humans.
(Some other animals may be affected, too, including cats, horses, and
wild animals.) Most cases of Blastomycosis have been traced to damp soil
containing organic matter - a perfect place for fungi to grow. Hunting
dogs and other dogs who are frequently allowed to roam are particularly
susceptible.
The fungus
may enter your dog through wounds, or it may be inhaled. As the fungus
begins to thrive in the dog's body, it spreads to the lungs, the vascular
system, or to the lymph nodes.
Symptoms
of blastomycosis include:
Weight loss,
chronic coughing, loss of muscle tone, shortness of breath, skin lesions,
red eyes, swollen eyes, excessive tearing of the eyes, and clouding of
the corneas
If you dog
has any of the above symptoms, you should immediately take him to the
vet. There is no cure without treatment, and the earlier your dog is treated,
the better his chances are for a healthy recovery. Without treatment,
your dog may go blind, or have other serious, life threatening problems.
Treatment
includes drug therapy, and may require several short hospitalizations.
Do not be alarmed if your dog's symptoms worsen at first; when the fungus
begins to die inflammation is common, and this can make the symptoms appear
stronger. When your dog comes home after treatment, his diet should consist
of high-quality food only, and you should restrict his exercise until
he is completely well.
Humans may
also become infected by blastomycosis. When handling your infected dog,
wear gloves and wash your hands frequently. (However, humans are much
more likely to become infected by an environment contaminated by the fungi.)
Valley Fever:
A fungus called Coccidioides immitis causes Valley Fever in both dogs
and humans. The fungus is found in dry, arid soil; when dust is raised
from that soil, the fungus is inhaled. Dogs who have been around construction
areas, who dig frequently, or are out in the wind, are especially susceptible.
Young dogs or dogs with weakened immune systems are also more likely to
develop Valley Fever.
Symptoms
include: A harsh cough, fever, lethargy, lack of appetite, and seizures
This fungus
is difficult to diagnoses and is sometimes mistaken for other fungal diseases,
cancer, pneumonia, cancer, or Lyme disease. If your vet suspects Valley
Fever, blood tests, x-rays, or antibody testing may be used to help diagnose
the disease.
Other fungal diseases in dogs include:
Aspergillosis,
which usually affects the nasal cavity and respiratory system, before
attacking the rest of the body. Dogs with long noses are most susceptible.
Symptoms may include open sores around the nostrils, bloody or puss-filled
nasal discharge, weight loss, fever, lethargy, and vomiting.
Cryptococcosis
is usually inhaled from the excrement of birds (particularly pigeons),
and tends to invade dogs' nervous systems. Symptoms include weight loss,
lethargy, head tilting, and eyes that dart back and forth.
Histoplasmosis
is caused by breathing in Histoplasma capsulatum, which is carried in
dust. Symptoms may include labored breathing, fever, anemia, and enlarged
liver or other organs.
Yeast Infections:
Yeasts are found on the surfaces of every living thing - including your
dog's body. When your dog is healthy his immune system can stave off and
destroy yeasts. But if his immune system is weak his body may not be able
to fight off yeast, leading to toxic levels that cause a myriad of health
problems.
In addition,
some breeds are more inclined toward yeast infections, including West
Highland White Terrier, Basset hound, Cocker spaniel, Silky terrier, Australian
terrier, Maltese, Chihuahua, Poodle, Shetland sheepdog, Lhasa Apso, and
the Dachshund. Also, any dog with skin allergies, an under-active thyroid
gland, hypothyroidism, diabetes, or who's had recent treatment with an
antibiotic or corticosteroid, may be more prone to develop a yeast infection.
Symptoms
of a yeast infection may include: Greasy or waxy skin, smelly skin, a
white tongue, hives or rashes, chronic infections, chronic cough, crusty
skin, and discharge from the eyes, nose or ears.
If your dog
shows any of these symptoms, he should see his vet right away. Since these
symptoms are general, and may be grounded in other problems, the veterinarian
will probably try to rule out other possible causes. Your vet may also
take a sample of the yeast on your dog's skin (with a cotton swab or piece
of tape, for example), or do a small biopsy and study it under a microscope.
Treatment
often includes treatment of underlying problems (like allergies or a thyroid
problem), topical shampoo or spray, and oral medications.
Yeast/Ear Infections:
Yeast are single celled fungus and they are used in brewing beer or baking
bread. Some types of yeast are less useful and that's the kind that grows
in your dog's ear. Yeast infections are probably the most common type
of ear infections in dogs. Because dogs have long ear canals that can
hold water after a bath, swim, or run through tall, wet grass. Add to
this a floppy ear that prevents good ventilation of the ear canal and
you have a warm, moist, dark environment in which yeast thrive. The more
moisture yeast get, the worse the infection will be.
Yeast infections
are most common in dogs that love water (Labradors, Retrievers), have
long floppy ears (Bassets, Beagles, Spaniels), have either narrow and/or
furry ear canals (Poodles, Cocker Spaniels), or have a history of ear
infections or allergies.
Symptoms
include: The inside of his ears will appear red and irritated; he will
shake his head and scratch at his ears almost constantly, sometimes to
the point of bleeding; a foul odor will emanate from the inside of his
ears; and he may whine, pace, or even stop eating because of the pain
and irritation.
Serious injury
or permanent damage may occur to the ears if an ear infection is left
untreated.
Prevention
and early treatment are the keys. In principle, yeast are easy to kill
if you keep in mind that they hate dry, acidic environments. If you keep
your dog's inner ears dry and clean by using an acidic type cleaning solution
made for dog's ears, you will make the ear environment very uninviting
to yeast. Acidic cleaning solutions are available from your veterinarian.
It is also
common to see a bacterial infection associated with a severe yeast infection.
Unfortunately, routine ear cleaning will not cure a serious bacterial
infection. Such double infections occur when yeast infections are not
treated in their early stages. It is more difficult and expensive to cure
this double infection.
Your dog
may also have underlying problems such as allergies and hypothyroidism
that can add to the seriousness of an ear infection.
If you see
no improvement in your dog's ears within 72 hours after you start cleaning
them, make an appointment to see your veterinarian as soon as possible.
You dog may need other medications to clear up the infections. If severe
irritation or a creamy discharge is noticed, see your veterinarian right
away.
Ear infections
can be very painful for your dog but they can be avoided with a little
help from you.
For pets
with itchy skin from yeast infections, use a Baking Soda rinse alone or
after shampooing your pets body with the appropriate pet shampoo for fungus
infections (see vet). It will be quite helpful with the overall itchiness,
skin problems and inflammation. Ask your veterinarian for his recommendations.
Baking Soda
Recipe:
Mix two (2) teaspoons of Baking Soda per gallon of warm water; make sure
to mix it so it completely dissolves - pour over pet, do not rinse off.
Mix 1 teaspoon
of Oxy-Drops + 1 cup of distilled water and use it to wash out ears (2
x a day) and to spray on itchy skin (2 x a day) or more until there is
relief.
The Bottom Line:
If you suspect
your dog may have a fungal infection or yeast infection, it's important
to give your veterinarian a history of where your dog has been, and what
led up to the first symptoms that you noticed. Sometimes such histories
need to go back as far as six or seven months. Explaining your dog's habits
may also be important. For example, if your pet tends to paw and dig at
gopher holes, this can be vital information for your vet to know.
So, with
a vigilant eye and a little sensitivity toward any discomforts your
pet may be feeling, you can keep not only your "best friend" healthy,
but your family and your other pets fit and well, too.
