My mare who I've had for 8 years just started weaving! No one else in the barn weaves, that I know of. And she's not doing it a lot...she does a slight sway on crossties. It's making me crazy! Does anyone have experience with weavers or do you think there's something else up with her? I notice no other neurological issues, no changes in soundness or behavior. She's still really sweet. Is it possible she was always a weaver to some degree and it's just becoming more obvious now because of something? I've never had a weaver before and it was a shock to see her start doing this after several years. She's been in the same barn for 4 years, and the only change is that the horse next to her left and a new one is there (but she likes him too). Her turnout paddock is the same. The horses next to her paddock are the same. It's very weird.
