About 9 weeks ago our 8 year old blenheim came down with a very intense localized itch on her right side that is towards the top of her back. She was in a lot of discomfort so we took her to the vet who first treated her for an allergy. This treatment did not stop the itching so we took her back and we've been treating her for sarcoptic mange. While her itching isn't as bad as it was at first, she is still in mild discomfort on a sporadic basis. Our regular vet and the dermatologist have pretty much ruled out that her itch is a topical itch caused by allergies or mange.
It's crossed our minds and been brought up that she could have SM although she does not have any of the "typical" symptoms. She does not "air scratch" and does not have any sensitivity around her ears, head & neck. She's been very healthy up until now and as I mentioned her itch which came on very suddenly is very localized. She tries to bite, chew, lick it. When i touch the spot it is sensitive. I know this can only be diagnosed with an MRI but does it sound like this could be SM?
Any thoughts would be greatly appreciated! Thanks!
