My mare travels wide in the back. Sometimes the vets want her to trot out twice. Now, most of them know that she trots wide in the back, and just make a note on the vet card at the vet-in. Someone said maybe the ones that trot wide may have a weak back... She's never had a sore back (except for the time we lost the saddle pad)! I think she's a strong, sturdy horse. She's 1/2 mustang, so I think she inhereted a lot of sturdiness (is that a word?). I guess she wouldn't do well in the show ring, but does fine in endurance.
And, on another note... I was going to drop Sally off at a freinds house near my work so I could leave at lunch time to go to the Jennings Boogie. I got to her house to unload Sally, and she had hurt her leg. Not sure where yet. I am waiting on the vet to call back now. She's 13yrs old, and I think this is the first time she has gotten hurt. Hopefully it is something that will heal shortly. There's always another ride to go to.
