Hayhut - Really expensive, but I still don’t regret buying this. I’ve noticed way less paddock scrapes than when they had a metal bale-feeder, it reduces food aggression, and reduces wastage.
Roundbale - Huge QOL improvement from both a management and a horse-health perspective.
Tiger Tongue - I’ve used this for everything - from grooming horses to getting mud off of rainsheets, scurff off of old tack, etc!!
Three Step Mounting Block - I just got one a month ago. WOW. I wish I got one sooner.
Pocket Pen LED Light - $6 at my local hardware store, clips to my coat front zipper, and SO convenient for after-dark feedings/checking horses over. Because it clips to my front zipper it’s perfect for picking out hooves after dark, etc.
Belharra Soap Conditioner - Expensive ($40 or so) but I could not live (happily) without this stuff. I use it on my Dublins and on revitalizing those bargain-basement/consignment shop tack finds, and it smells amazing and really extends the longevity of tired leather.
Fig Newtons & Gingersnap Wafers - such a game-changer for sneaking in pills/medicine and liquid supplements (like APF).
EasyCare EasyBoot and Easyboot Epic - I use these boots for when horses pull shoes and/or have abscesses, instead of dealing with the hassle of wrapping, duct-taping, etc. I still pack the sole, wrap with diaper and vet wrap, but then just slap the boot on. It stays on great in all conditions (horses are out 24/7) - I do notice the EasyBoot with velcro does not stay on well in deep snow (1-2ft), since the snow gets stuck in the velcro. The Easyboot with wire, however, works excellent on staying on 24/7 especially if you wrap hoof with vet-wrap first.
Livestock Drench Gun - GAME changer for me for the horses that have multiple medications that it is imperative they eat. Rather than mix into feed, I load it into a drench gun and give orally. It works so much better than dosing with a normal oral syringe as often I’ve found the oral syringes can get blocked/plugged and be difficult to load up.
