Our 2-1/2 yr old Vizsla has developed a skin rash on her chest. It appeared two months ago and went away with a course of antibiotics, but now it’s back.
She eats Orijen, a high-quality fish kibble, but also gets occasional food treats. She swims often in an area of Lake Ontario that is probably filled with bacteria.
Is there a systematic way I can begin to treat her, before taking her to the vet?
