Hi Lynn,
you have it all wrong a dog will only react to starchy carbs if he has food sensititivies, Sweet Potatoes, Tapioca, Potatoes, Rice, Oats, etc do not cause yeast Dermatitis in dogs, I have a dog with IBD, Seasonal Evirvonment Allergies & Food Sensitivities I thought the same years ago until my vet explained he has food sensitivities & was put on a Hydrolyzed vet diet which was 60% carbs, we do a food elimination trial, & you keep a diary & as teh years pass you will see a Pattern as environment allergies can also cause Yeast Dermatitis as well Patch gets yeasty smelly paws from foods & environment & itchy smelly skin when he eats foods he’s sensitive too Chicken, Tapioca, Carrots he get itchy ears & shakes his head, he does real well on Sweet potatoes & Potatoes especially for his IBD, if you look at the vet diets for skin & food allergies they have Potato & a novel protein, it’s good to feed dogs a low carb diet but starch does not feed yeast, here’s Dr Karen Helton Rhodes a Dermatologist link “Facts & Myths about Yeast Dermatitis in Dogs”, Dr Karen Helton Rhodes is also on a F/B group called “Dog Issues, Allergies & Other Information Support Group” you’ll learn some really good stuff in that F/B group lots of help http://www.healthyskin4dogs.com/blog/2015/9/8/facts-myths-about-yeast-dermatitis-in-dogs,
Start your dog on an elimation food diet, 1 novel protein & 1 carb & bath weekly or twice a week if itchy & smelly bath in an antibacterial medicated shampoo like “Malaseb medicated Shampoo to kill the yeast & to wash away any allergens on the skin.. also make sure you increase the omega 3 fatty acid in your dogs diet, feed foods like Tin Sardines & Tin Salmon in Spring water add 2 spoons to 1 meal of his a day or give 1 Krill Oil capsule a day with a meal.
