Question for you guys: what makes a horse cross-fire at the canter on the lunge line?
She only cross-fires on the lunge-line, but NOT when she’s loose or under saddle on a circle that’s the same size as the lunge line. She cross-fires the same in both directions, a little more so when she’s excited and a little less when she’s relaxed. She drops her shoulder to the inside when she does it, so I’m inclined to think it’s a balance issue. She usually picks up the wrong hind lead right from the get-go. Sometimes she’ll throw in a flying lead change (in both directions) with no apparent effort.
She’s 100% sound and barefoot, cleared by the vet and adjusted by the chiropractor a couple of times. Neither found anything of interest. No areas of tenderness and she is NOT a stoic horse. If she was hurting, we’d know. She’s done this since I’ve bought her two years ago and she’s gone through varying periods of light to heavy work with very little change in the cross-firing, ridden both by me and a professional trainer. Her walk and trot are both quite lovely and she swings nicely through her back and is very light in the bridle.
The mare in question is an Arab/Saddlebred cross, with a fairly short back/compact build and very, very athletic, 7 y/o and 15.2hh. She lives outside, but it’s been super icy and she’s smart enough to only walk and maybe jog a little bit, so she’s pretty out of shape. I had surgery last fall so she’s been out of work since October. We’ve had maybe 6 rides back and I’ve only cantered her very, very briefly under saddle a couple of times since we’ve been back with no cross-firing. FWIW, she is slightly base narrow in the rear.
We have a very small indoor arena (maybe 60 x 80) to ride in and it’s too icy to ride outside right now. Suggestions for activities that might help her to improve? Thanks in advance!
