I recently took on a bit of a project in the form of a four year old AQHA WP filly. This girl is really sweet, has the classic WP form and movement, and is very well bred. She also has been shown extensively in the AQHA circuit as a futurity horse.
The only problem is that she is EXTREMELY dull sided. I watched a video of the previous owner riding her and this gal had her spurs on this girl the entire ride to get her to trot and canter. Now the woman that I am working this horse for doesn't want to wear spurs, just wants to lightly show, and mostly just enjoy her horse, but there is really nothing enjoyable about riding her right now.
I have never delt with a horse that is this unresponsive, she doesn't even seem to notice when I just use normal leg cues to ask her to move out and transistion up. If I don't keep my heel on her constantly see immediatly stops too. I have only ridden her a couple of times, just to see what she knows and what we need to work on (she has a very false headset which is going to be fun to correct), so I haven't tried my only idea which is to carry a crop and use it to reinforce my leg cues, but obviously you can't carry one in the WP show ring. Any suggestions would be greatly appreciated!
