Not quite the same as I've always been horsey so DH (to some extent) knew what he was getting into, but I wouldn't call us a horsey family as such, me and DD1 are horse mad and always have been, DH and DD2 are occasional, take it or leave it riders and DS only really likes horses from a distance! We got our first pony for DD1 (I'd had my own horse when we were first married but gave up riding for pregnancy/baby days) when she was in year 5 so 9 turning 10 and we had ponies pretty much constantly from then onwards.
Do I regret it, the short answer is no but obviously there's a much longer answer too, I think anyone that has horses and says they've never a flicker of any doubt or regret is either very lucky or outright lying. There's no doubt horses take up a huge, huge amount of time, money and energy and my biggest regret is probably that doing this incredible thing for DD1 did inevitably mean DD2 and DS got dragged along for the ride (pun intended!) as only somewhat willing passengers. We were/are very lucky that financially we could invest in their hobbies and interests equally to DD1, and time and practicalities-wise DH picked up a huge amount of slack ferrying them to different places and supporting practices and attending concerts and matches and so forth while DD1 and I were busy with the ponies, and he gained enough horsey competency to supervise DD sometimes and do yard jobs while I attempted to occasionally not be a total stranger to the other two
. Seriously though I did often feel pulled in far too many different directions (although I think that's normal enough with 3 very different kids with separate interests) and between that a full-on job to afford it all it didn't leave me very much time for myself (I was/am lucky enough to be small so I could ride DD's ponies on occasion but realistically they were her rides, I didn't get much of a look in). And I have to be honest that it did impact things like what holidays we could take, what we could do at Christmas and so on. Plus the emotional impact, we had a real bad run of luck with colic and injuries and lost two ponies in short succession which was just absolute heartbreak for the whole family as we all loved them as pets as well as DD's hobby.
So yes, there's no way I would do it without DH 100% behind it and stepping up ++ to support, plus way more financial stability than you even imagine you'll ever need as the expenses are endless. But if you have those two things covered then it's so wonderful owning your own, a pony-filled childhood is the happiest thing imaginable for me and the skills and resilience they learn from riding are second to none.
But that being said I do think there's absolutely nothing wrong with saying that it's not the right thing for the whole family and finding other ways to get your DD pony time that aren't quite such a huge commitment, lots and lots of pony kids are not ever lucky enough to own their own and the truly determined/commited ones will usually find a way, helping out on the yard, shares/loans, riding holidays, own-a-pony days, PC membership as a non-owner, there's lots they can do... Or (they tell me!) it is possible to reach a reasonable proficiency and enjoy weekly lessons or hacks alongside other hobbies and interests without it becoming an all consuming addiction, I can't imagine this personally mind!
