Yah, a "husband" horse is totally, IMO meant to imply the type which you buy so that you can DRAAAAG your husband out riding with you every so often, as Dee said, and it will take care of him, be "bomb-proof", etc...However, I think it just as easily could considered a "wife" horse were the husband to be the "rider" in the family...unfortunately though, in total honesty, (other than men who ride while doing their cattle ranching work, or ride rodeo, or race...) in the U.S., how many men do you hear about going down to the barn all evening after work and all day Sat and Sun, just to groom and visit with their horse, possibly take it for a short ride every evening??
Not to say men COULDN'T do so, they just, well, really generally don't! (More often then not they will be golfing, or out mountain biking, etc...while their wives are at the barn...it does tend to work out that way usually!)
I don't think it's meant to be sexist...I think it is a true evaluation of the "second" horse in the family which is just as loved, will likely be ridden and cared for primarily by the wife in addition to "her" main riding horse, though, that would be the one hubs would ride generally ride more often than your horse when there was an option!
I don't believe it is meant to devalue
the male at all...in my opinion, ANY man who is willing to participate in riding alone, or, especially with his wife, watching his wife ride in her lessons/spending some of his free time hanging out at the barn with her while she grooms her lesson horse, etc... is an AWESOME husband...(I have one of those
!!)...and when we are ready to lease/buy horses, we will EACH have "husband" type horses
, hopefully...as this would be a first horse of our own for EACH of us!
