Yes, I have a puggle/ jack russell mix who has had this same annoying problem. And I work at a veterinary clinic, and so thankfully i get discounts. Because this is a non stop problem. ANd he is doing very good right now. Its is also Ketoconazole that works for him. But it has some bad side effects so you cant keep them on it permantly althought i wish i could. I just give it to him for a week every time he starts to smell yeasty. ANd also give baths with Hexadene three times a week. ANd he doesnt smell like yeast anymore. I also give him Zyrtec for whatever it is that he is allergic to. And this helps alot with the itching. We also have done skin scrapings. And he eats a grain free food. Also yogurt , plain yogurt is very good for dogs with yeast infections. I add a tsp to their breakfast every morning. Hope this helps |
