I have a Labrador Retriever that is about 3 years old, and hes on his 4th yeast infection within the last 6 months. Poor baby :( I have been back and forth to the vet getting antibiotics, antifungal meds and prednisone.The vet has done thyroid tests (came back normal), and skin samples to ensure it is not any kind of mite etc. I have tried changing his food multiple times, but nothing seems to work. He gets treated and gets better then within a few weeks gets it right back again :(. I have inquired about the new “allergy test” that is VERY expensive 500.00, and have friends that have had it done with a non-conclusive result. I am wondering if anyone out there has any good advice for me? I am looking for a good food that will not trigger a yeast infection. One I am looking at is by IAMS and says its for “sensitive systems”. I am almost at the point where I may just feed him a diet of chicken and rice, its a lot of work but if it helps Oliver its worth it. Thanks in advance!!
