Absolutely. When I got my gelding he was lazy beyond belief. I tried him out at the property and was constantly kick kick kick, always at him it was just annoying, but I liked him and got him anyway.
When I got him home he was the same for a few weeks, until we got used to each other he was really lazy and unresponsive... Now he does exactly what I want when I ask for it. The only place he is still lazy is in the showjumping ring
but that's not bad, he still jumps everything he just doesnt rush at it
