So here is the history and dilema. I have a Sharpei/lab mix, she has some of the wrinkles of a sharpei and the coat type somewhere between the two breeds. We have fed a dog food with no issues, until last summer we switched slowly from our brand to Pedigree as we were watching a relative's dog who is on pedigree. A few weeks later she started having hot spots, then got fleas from a dog, probably the neighbor's dog. We dealt with the fleas, which took a long time, and the hot spots... She also got stung by ground bees during all of this, and a quick visit to the vet and prednisone and benedryl shots.. and pills.. We thought we had it licked (so to speak), baths, sprays, medication... We had her on a different dog food, and that was fine, we were slowly starting her on a different style (probably a different recipe) of the same brand of our normal dog food, and she has started chewing on herself, but its not hot spots. It must be a type of dermatitis, similar to a hot spot.. but after chewing three bald spots on her tail, and finding scabs under her fur, causing her fur in small areas to start to fall out as the scab heals.. Just not sure what this is. I have tried something similar to Bitter Apple, she seems to have acquired a taste for it... We have her on a grain free diet for 2-3 weeks and are slowly introducing her to the original dog food we had her on. Our border collie mix shows no signs of any hot spots...our sharpei mix also licks alot, before chewing... And more bathing with a medicated shampoo, rinsing very well... i have found the only thing that stops her now is I have a t-shirt on her, she seems to prefer my DH's shirt to one of mine. Any ideas that can help with this?
