In 2005 I adopted a filly when she was just 12 hours old because the vet thought that she was a dwarf Miniature Horse. I am thinking that perhaps she is an Achondroplasia type dwarf, but not sure, it will be interesting to see how she matures.
Anyway, this filly had one front leg bent back when being born, the breeder was able to get her leg out in front of her and get her delivered, but it took her a long time, and she had to pull very hard on her legs. The filly had very crooked front legs, her knees were swollen and she was over at the knees. She also had tendon laxity in her back legs which left her walking on the bulbs of her heels instead of her hooves. The vet trimmed the "baby slippers" off of her hooves when she was about 12 hours old, but this is what her back legs and hooves looked like when she was only 21 days old.
I took her up to Texas A & M to have Dr. Honnas trim her for me, thinking that perhaps she would still have to wear the shoes after her trim, but as you can see in the next picture, she was up on her hooves perfectly and did not have to wear her shoes!
Update on Toy: 1/2006
Here's a picture of Toy's front legs before I made a toe extension on the right front hoof with the SuperFast glue. As you can see, the left hoof had improved greatly!
After 1 week of having the toe extension on, I took Toy back up to Texas A & M and asked Dr. Honnas to trim her hooves for me again. He lowered her heels on the front hooves, but left the toe extension on, and said to leave it on for a couple more weeks. I think applying the toe extension before taking much of any heels off for a week, was good; as it was a more gradual change for her
Unfortunately, I lost my little Toy in July of 2011, do to internal bleeding, which my vet thought was most likely due to a tear in her aorta.
