I just saw that my eight months old pug has a little patch of very rough and dry skin where she is missing hair. This patch is about two inch long at the very base of her tail. We never saw this type of patch before, so the patch may be formed recently in her tail. She hasn’t been itching it and isn’t missing her hair anywhere else. She also doesn’t seem to care when I touch it. What could be the cause behind this, what should I do, and can I set up a vet appointment? Please reply soon.
