A mature welsh/arab pony mare I own is at it again. Every
year around March 1 she starts rubbing her neck about
halfway down on both sides. Rubs until it is raw and will
keep rubbing after that if I don't put her in a hotwire pen
with nothing to rub on. This has been going on for about
five years now. Starts around March 1 and lasts for about
a month. My vets have very few ideas.
No other horses in our herd are similarly affected. The
full sister of this mare has no such problem. I've tried
treating for lice, wormed, fed flax (but she doesn't need
the extra calories). Only thing that seems to help is
spraying with Silk; that seems to make her more comfortable. After about 4-6 weeks the mare stops
rubbing and the new summer coat comes in and all is
forgotten until the next year.
Help, is ther anyone who has found how to stop this?
My pony did that one spring. Rubbed all of the hair and skin off of his neck both by rubbing on fence posts and by scratching with his hind legs like a dog. We gave him Dex on the assumption that it was an allergy of some sort. It alleviated the itching and scratching and he hasn't ever done it again (I don't think that has anything to do with the Dex, just that the particular cause of the itchiness hasn't come back around). It was very strange and my vet just kind of shrugged and said that sometimes happens.
This is the second time I've seen someone writing about this same situation today, tis the season ;-) Look up Sweet Itch, it's very common and it's a pain in the butt in the spring,sometimes summer..... might be your issue.....
Check for lice. Late fall and late winter. It says you've treated her for that but have you really looked hard for eggs/varmints on the hair? They are small and easy to miss. Treatment is full dose ivermectin every 7 days x 3 and lots of topical lice powder.
If that doesn't work, spirulina--the stuff is amazing! One of my friends has an App that used to rub himself raw/bloody even on Dex. Once he was put on spirulina, he was totally fine. I even started using it for myself because I have seasonal skin itchiness, and it completely cleared it up with the spirulina.
