Hello and thank you for asking your question on just answer. My name isXXXXX will try to help.
Is she scratching at her ears more than usual?
is she on any medications?
There is a rough test, for sarcoptic mites, and your rub the tips of the ears. If she immediately starts scratching with her hind foot, it could be sarcoptic mites.
If she had sarcoptic mange, and that usually affects the ears, then she would be scratching at her ears non-stop. It causes severe itching.
I am thinking she may have vasculitis. Vasculits is inflammation of the blood vessels. It can affect the tips of the ears. It can happen from an autoimmune reaction or an allergic reactions. It often happens after vaccines are given. Infections can cause it as well. Medication is given to stabilize the lining of the blood vessels and control inflammation.
It is not life threatening so it is not an emergency.
It does usually go away after a few weeks of treatment.
Yes, I would take her to your regular vet to have her checked.
I thinks a skin scrape, just to make sure there is not mange, is a good idea as well. If it is mange she can take an oral medication to clear it up.
