I have one horse, Odhinn, who is a 5 y/o Swedish Warmblood gelding. We do our best attempt at dressage...
We are pretty easy to please!
Odhinn needs a new halter (breakaway) size large, I am a firm believer that you can never have *too* many brushes

. Odhinn loves treats of all kinds. I like boot socks to make it easier to put my boots on, and we could also use a decent dressage whip. Umm... I love horse shampoo or other useful things, really. I would love to have some of the decals for my Truck window (the kind that you can peel off) for dressage or Swedish Warmbloods..I could use a good first-aid book, or a book on how to clip. I can always use winter riding gloves or those nice fleecy things that keep your ears warm!!
I am pretty easy to please, and prefer practical/useful things to decorative things, as I am not much of a fan of "knick-knack" type of things, even if they are horsey.
Hope this helps
