Commercial Treatments

Commercial treatments for foot fungus in dog paws include anti-fungal shampoos, and creams and ointments that contain steroids such as Ketoconazole and Itraconazole. Wash the dog's skin and paws with the shampoo first. After shampooing, apply anti-fungal ointments to affected paws and wrap them with bandages. If you cannot keep bandages on your dog, the animal should remain indoors for three or four days until the paws heal.

Sulfur Treatment

Sulfur-based soaps and shampoos are effective in curing yeast infections in dog paws. Bath the paws in the soap or shampoo at least two times per week until the fungus has cleared up.

Apple Cider Vinegar and White Vinegar

Raw, unprocessed apple cider vinegar works as an effective rinse in the treatment of any yeast infection, including those in dog paws. Use about 1 cup of apple cider vinegar in 1 gallon of water to make the rinse. If your dog's paw pads are split up or otherwise contain open wounds from excessive biting, refrain from using the rinse, as it will burn and cause irritation to the paws. Another option is to use 1 to 4 cups of white vinegar and 1 cup of hydrogen peroxide in a gallon of water to treat yeast overgrowth in paws. Both treatments should be administered once or twice daily until the infection clears up.

Additional Treatment Options & Tips

You can also use lemon to make an effective anti-fungal rinse. Use the same measurements for lemon as for apple cider vinegar. Another option is to use 20 drops of peppermint essential oil in a gallon of water to treat yeasty paws, or use a tea tree oil shampoo to bathe your pooch.
If using lemon as a yeast treatment, note that it might bleach dark dog hair.
Avoid getting any rinse in your dog's eyes.
Use a cone collar to prevent your dog from constantly licking and biting her paws. Keep your dog away from moist areas while she is being treated for fungus.
