Allergies or chronic yeast infection? Usually the smell is the yeast . Your vet should know what todo! Antibiotics and steroids don’t do either but work on the infection and inflammation.
First time round with this did you use malaseb shampoo? Head and Shoulders contains exactly the same anti fungals, and a trichologist friend uses it on his cavapoo.
Raw spots are nasty, and get infected easily, my springer had this as part of an autoimmune disorder. They spread within hours, and can join up to make large areas. She had antibiotic ointment for this . Then the hair took a six month cycle to regrow.
The sites of yeast are usually in hairy feet, hairy ears and lip folds, and it really smells musty.
I’m not against natural remedies, but I like to know what the ingredients are. You need to be careful,because tea tree oil and cider vinegar for example, are very unpleasant on broken skin.
Ears need trimming and cleaning weekly, with something the vet recommends.
What is his breath like? My rescue terrier had 28 teeth removed,and he stank before. Is their any gum or lip fold problem?
If the vet eliminates a yeast issue, I would suspect an allergy , which could be one of a hundred things. The online tests with saliva or hair are proven to be inaccurate, though that’s another post. The vet ones are best.
Do let us know what you try. It’s not easy and results are slow.
