A few months ago, my mare got these sores on her anus and labia. The sores were pink and yellow (her skin is black) and they looked rotten. The ones on her anus were much nastier than the ones on her labia.
I got my vet to look at them and he said he didn't know where they came from, but that they were going to be hard to get rid of because of how difficult it will be to keep the area clean. He gave me some chlorhexiderm shampoo and an ointment he made by mixing a few things together. He told me to shampoo the area and apply the ointment twice a day, then once a day, until the sores are gone. He told me they were probably going to come back, and they did, but only the ones on her anus.
Is there any way I can keep the area extra clean so that they stop coming back? I can hardly wash it every time she goes to the bathroom...
Would a tail wrap help air the area out and keep it from getting warm and sweaty? Is it safe to keep tails wrapped?
