Thanks for the suggestions guys ^^
Para - With Selena it was just a matter of her being SO sluggish when being ridden or worked. I could literally come to the point of beating her to move and she just wouldn't. We thought maybe she needed something like that so we gave her the block, and she got instantly better and can now run, slide, turn, amazing and all but she has just lost interest in it and isn't licking it anymore for some reason no matter what I do to it. The vet suggested I get something else.
Pssh.I didn't pick up the wrong lead
It's called a counter canter...
...A very advanced maneuver.
