I did the same thing :) I was so excited to get a horse that I went out and bought everything I could! Which, it turns out, was very useful!!! Anytime the farrier or the vet come and ask me if I have a specific product, I usually do, LOL. Although to be honest, I probably bought a lot more than I really needed. But because there is a lot to buy once you get the horse, it's nice to have a few things to start out.
I guess we need to know whether you will be boarding your horse and what is included in the board. But other than grooming basics, you should have some of the following:
- lead ropes (at least two, but I got two ropes and one with a chain which I have used once or twice - the two leads have served well as improvised cross-ties between two trees when I want to groom outdoors)
- lunge line and lunge whip (and maybe side-reins if you think you will want to use some for lunging)
- shampoo and stain remover (I like Cowboy Magic spray for quick touch-ups)
- powdered thrush medication (my trimmer says always to use powder and this one also works for rain rot, etc.)
- ointment for scrapes and minor cuts
- fly spray (but you may only need this certain times of the year depending on where you live)
- a first aid kit containing anything else you will need to treat an injury, although if you are boarding, chances are there is one in the barn
- a clipper set that includes scissors
- buckets (not just for food and water - you will want a bucket or two for washing, along with sponges)
- lots and lots of old towels have come in useful to me for all kinds of things from drying him off after a rain to spot-washing
- absorbine spray to apply on sore muscles after a good workout
- I like to keep a kettle at the barn for warming up water, but if your barn has hot water, this is probably not necessary
I'm sure I'm leaving stuff out... You will want a lot of extra barn clothes for yourself too. Even though you may be taking lessons now, when you have your own horse, you will want to be at the barn as much as possible and in all kinds of weather. I now have a whole side of my wardrobe dedicated to horse clothes ;) It's a grand adventure! Enjoy every minute!
