I had taken my dogs to several vets closer to home in an effort to find a workable regimen to relieve them of chewing their paws. They have no fleas or ticks, are bathed regularly and are indoor dogs. After being given all unsuccessful remedies and having them suffering with an obvious irritant to their paws, no relief. I was referred to Dr. Armstrong and decided to drive the 35 miles to try one last possible solution. Sure enough, without unnecessary tests, he said they had an allergy. He then gave them each an injection. I brought them back once a month for the injection and sure enough .... within a week, they had stopped licking their paws. BEST VET ROCKS!!!!!!!!
