I have 2 w/yeast issues, confirmed w/skin cytology...Momo gets 'frito' paws & is an obsessive paw licker & Princess gets brown gunk in her ears & turns into an itchy mess. Absolutely no sugary foods or carbs as this is food for the yeast (i.e. potatoes, sweet potatoes, molasses- in some treats, grains- some are ok, like quinoa, millet, they're technically seeds).
Coconut oil is great, it's anti-fungal/ bacterial/ inflammatory!
Finding a grain free, potato free kibble is hard but not impossible. Good ones we've tried are Canine Caviar & now they're enjoying Nature's Logic. They also do great on the coconut oil & reg line of Party Animal canned food & Nature's Logic can too.
This is an excellent vid/ read about yeast & how to treat/ manage them.
