@dreamskape My Dog never had any skin conditions at all. The only time she was ever sick was when she had Cancer.
My Mom has had dogs that had Hot Spots and she is a Nurse and knows more about Drugs than anyone I know and she did not use Steroids like Prenisone because that is very hard on the Liver. She used a combination of heavily diluted Lavendar Essential Oil which is great for calming affected areas.
She mixed that Eseential Oil with Distilled Water and kept it in a spray bottle. It was great because it worked.
DAIRY Causes Yeast Infections so I would stop that post haste. No more Bovine anything. Your Dog cannot tolerate it and rightly so because Cows make milk for their Babies and that is all. I am a Vegan and never liked Milk even as a child.
Try taking away the Yogurt and the Bovine Colostrum and the yeast infection should clear up. I not then get a fube of Monistat which is for yeast infections and put that on the Paws. That should help.
