I don’t get the whole “mareish” thing.
There is this belief that mares are temperamental, difficult, mean, etc. That is just not true. A horse is no more likely to be any of those things because she’s a mare.
To me, the only noticeable difference between neutered male animals and unaltered female animals is that sometimes, the geldings are more “what you see is what you get” with their reactions. Mares sometimes have a wider range of reactions, which does not make them automatically inconsistent or difficult. I actually prefer that variability in a riding horse; I feel like they can be more tuned in to the situation.
Sorry for the derail, it just bugs the heck out of me when one of my mares exhibits an undesirable behavior that all horses are capable of exhibiting, yet someone responds with a snide, “well what do you expect from a mare?” She didn’t do that because she’s a mare, she did that because she’s a horse. Almost like remnants of a strongly misogynist society.
As for the occasional mares who are a pain in the butt when they are in season with incessant squatting and peeing, I’ve had just as many geldings who are horn dogs, unaware that they are missing critical hardware to get the job done. Mares don’t hold the market on that, and I’d much rather only deal with it every few weeks when than year round. Although I’d prefer not to deal with any overly hormonal animal— mare, gelding, or stallion (or person for that matter).
