My dog has serious allergies...itching, whining, hives, swelling, intermittent...we've tried it all (essential oils, limited ingredient foods, steroids, benedryl, ear mites medication, scabies medication, raw diet, and more!). Any recommendations for a GOOD Dr. ? We've tried Palmer Vet, Northstar, Far Country. No one knows. The next step is a dermatologist, but $$$. Looking for anything other option.
