Yeast infections are becoming more and more the next rabbit hole for uninformed pet owners. If you look into what is yeast and yes there is more than one for dogs, but really what is yeast? It is a fungi, that most animals have as part of their biological makeup, however the issue is when it wants to be king of the body.
The way that yeast normally wants to take over, is by being feed more of it's diet than the other good flora in the body, ie. more carbohydrates and sugars which it loves to ferment, and that is when we see it show itself, in the ears, toes, red rashes etc. So the easy answer to help keep yeast in check is feed biologically appropriate diets, to our furkids and ourselves. So keep all of the sugars and carbs away, and get back to natural.
The following article link from Dr. Jeannie Thomas in March 14, is a must for explanation and to get you on the right track for healing. Have a go at this before $000 in surgery / antibiotics / steroids that just mask the issue. It is a great read and will really help in guidance.
