Yeast on a dog's skin is an indicator that the dog has a compromised immune system. The immune system can become depressed through a number of channels including diet, exercise, vaccinations and antibiotics. In order to cure the skin yeast infection, the whole health of the dog will have to be brought back into balance through diet, intestinal flora, enzymes and topical skin treatments.
Grain- and Potato-Free Dog Food
One of the main underlying causes of a skin yeast infection for a dog is a diet high in carbohydrates. Dogs are carnivores and cannot efficiently digest and assimilate grains and starchy vegetables. The best diet to feed your dog is one with only raw meat and bones. This option, however, is not practical for most families. There are grain- and potato-free dogs foods available at some pet supply stores. Putting your dog on a grain- and potato-free diet will starve the yeast organism and help to clear up your dog's condition quickly.
Feeding your dog unflavored yoghurt up to three times daily will give him the probiotics needed to re-establish a healthy intestinal flora. An immune system will not function properly if the intestinal flora is off balance. Antibiotics are the main culprit in an unhealthy balance. If your dog does not like the taste of yoghurt, try any over the counter probiotic capsule. Open the capsule and sprinkle the contents either over the dog's food or in his water.
Apple Cider Vinegar
Raw apple cider vinegar, which can be found at your health food store, added to your dog's water daily, will give your dog enzymes needed to combat yeast. Add 1 to 3 tbsp to each bowl of water. If your dog does not like the taste, decrease the amount added. Apple cider vinegar also may be used as a topical spray to relieve your dog's itchiness. Mix 1/2 cup of apple cider vinegar with 1 cup of water. Put the mix in a spray bottle and spritz your dog whenever he needs relief.
Tea Tree Oil Salve
Tea tree oil is an anti-fungal essential oil. You will need to mix 2 to 3 drops of tea tree oil into 1 tbsp of coconut oil, which is an anti-fungal carrier oil. Do not put the tea tree oil straight onto your dog's skin as it will burn and sting her. Apply the salve to your dog's skin several times a day. This mixture may be used in conjunction with the apple cider vinegar spray.
