I have a soon to be 10 yr old maiden mare who was bred last in July of last summer. She was checked by my vet by palpation in January and my vet stated she wasnt pregnant. Yesterday as I was grooming her, I noticed her teats area was swollen and also some crust formation was noted. I have attached a picture of her area to see if anyone had an idea what I am looking at? She also was wormed by panacur powerpac several weeks ago but has been rubbing her bum against the barn constantly. I was planning to keep watching to see of any changes and if so, probably contact my vet by the end of the week if so..thanks for any ideas!! ;)
