What else can I do? Training ideas
Finn is a yearling Shire cross so starting work under saddle is several years off. He has impeccable stable/ground manners, will lunge well either direction, backs, pivots on fore and hind, loads in the trailer readily, has been ponied on trails a good bit and will go through water etc, has been desensitized and is completely unphazed by cones/tarps/blowers/clippers/bridges. He ground drives well now, has gotten comfortable in and been lunged with a very light (8 lb) pony saddle, and most recently mastered sidepassing on lead. He learns very, very quick and seems to have a real thirst for learning new things. He's super eager and willing to please, and I want to continue to encourage that trait. I want to be able to keep his skills sharp and continually introduce new things, but I've run out of ideas. The instructor I'm taking english lessons from suggested starting to lunge him in a training surcingle and teach him to set his head, but I've never used one and am hesitant to try without having someone show me safely how to do it.
So I've kind of come to the point where I've taught Finn everything I can think of in terms of groundwork right now, and while we will continue to work on that regularly I'm wondering if anyone has any neat ideas, handy tricks, or fun stuff I can work on with him for a while!
