Have a 2 yr female. She developed a spot where she was losing hair on her side.about 1x2 inches. Ran all the tests for skin disease and thyroid. All came out negative. Are vet concluded it was a reaction to her rabie shot. It is exactly where he gives her shot. He thinks the hair will never grow back. She has a beautifull coat except for this. Any rogain for dogs??? Any one had a similar situation with a shot?
