Hi, my mixed breed 4 year old dog has the tips of his ears dry and covered in little wounds. Also there is no fur on the affected area. Its been like this for a couple of years. He's not in pain, it's not itchy. We've been to the vet, they took scrapes and blood and £400 and said that they can't find anything! So its not an infection and there is no parasites involved. I moisturise his ears with primrose oil at the moment and at least its not dry, just reddish. I thought it might be a vascular problem, in this case it's incurable. But there must be the way to keep it under control. Any advice or suggestion will be greatly appreciated. Thank you
That looks like a vasculitis. Leishmania can cause that, make sure to test Blinchik If you have travelled to endemic regions.
There are many other causes for the ear's border vasculitis, take Blinchik to a veterinary dermatologist, they will absolutely know what to do and how to treat it.
