I bought these boots for my girl for the front legs. They are pretty inexpensive, just to keep her from snagging her inside front ankle with her opposite foots shoe nails. She doesn't clip with the back feet, just now and then with the opposite front. Anyway, this solved my problem.
Dover Saddlery | All Purpose Galloping Horse Boots.
Here's my question: Can I use the same boots on the hind legs? I contacted Dover and the person who responded to my email said he uses the boots himself and they can be used front or back, with obviously needing a size larger for the hind legs. I just want the same boots on the back for the look. I'm a little vain like that.
I did check out hind boots and the ones they have at my local saddlery shop are like 3 times the cost of these and the only difference is they are a little longer with four straps instead of three.
