Goodness no. I understand where you’re coming from though. Especially in regards to discussions online where there are so many opinions and some of them very strong, and it’s easy to feel like you’re an absolute failure and borderline abusive if you’re not spending every last dime and resource and bit of time and energy you have ensuring that the horse never has a single moment of discomfort or inconvenience in its life.
It seems there is always more that we can be doing to be “better” caretakers of our horses. Feed and supplement companies thrive on this mentality. Everyone wants to give their horses the very best of everything, but there comes a time when you have to realize that there is a limit, and that is personal to each individual who owns a horse.
You are a conscientious owner who is doing just fine by these lucky horses. A lot of the advice and suggestions I see in forums like this one and others tends to assume a “perfect world” situation that just isn’t the reality for most people. And you’re not failing the horse by not providing it a perfect world. There is only so much we can control.
ETA: Wanted to add that when I look back on my care and riding/training of some of my former (now dearly departed) horses, I cringe and wish I could speak to them one more time to beg their forgiveness. But those horses, by all accounts, had great lives. I loved them, I did the best I could with the knowledge and resources I had within the circumstances I could not change. I know one of my show horses almost certainly suffered from major neck arthritis and gastric ulcers. The signs are crystal clear to me now in hindsight, but when I had him I thought he was just “stiff” and “quirky.” I had another gelding who definitely had metabolic issues and who injured a leg that I did spend a lot of money to fix and he did well, but in later years I got slack and figured he was “fine” when he probably wasn’t. But he was loved, fed, kept up-to-date on feed, teeth, vaccinations, deworming, etc. He was happy.
I know a lot more now and I also have just one horse now. He’s the best cared for of any I’ve owned over the past 36 years, but it’s still not “perfect” by any means. I started him too early (2!) and I think there are residual effects even all these years later (almost 17 now). Nothing major, but it’s still something that I know wasn’t right. I used a subpar farrier for MANY years who did not do any of my horses’ feet any favors. I didn’t know any better. He was a nice guy, he came every six weeks on the dot, he did the horses without me being there, and he was an honest, hard-working fella. He knew what he knew and I knew what I knew and when I learned more, I had to let him go and hire someone more qualified.
Anyway…the point being…your horses aren’t suffering and neither were mine. There are plenty of horses that truly ARE suffering that would trade places with them in a heartbeat.
