Chicks sells the small mesh hay nets, for less than $9 each. Are you familiar with kissing spine? The closest comparison is low back pain in humans. I've seen people with low back pain walking in a peculair fashion in an effort to reduce the pain. This generally occurs in shorter backed horses.
I never heard of Kissing Spine until it was mentioned recently...maybe by you? I did read some about it. Chiro never mentioned anything about it when she checked her. I'm thinking she really felt there was something else going on that wasn't spinal. For now, I will continue on the EPSM route and see where it gets me.
