When people lunge the willies out of horses it drives me nuts!!! Horses have 23 hours a day to play and be goofy. When I take that one hour I expect them to behave and keep their focus on me.
Bratty Mare is the one who has gotten me to work lunging into my training program. I tried for awhile to scratch lunging out of her training program but I found she just wasn't keeping the same progression. She does well with once a week having lunging in the pessoa system. We work on transitions and keeping her focus on training and forward engagement. She fakes her forward really well by throwing herself on the forehand and going fast, but not a proper forward. When I ground drive her and lunge her it really helps to get her to focus on proper forward.
These are the woof boots I love for schooling, trail riding and even eventing lower levels Woof All-Purpose Boots | Dover Saddlery
My favorite pair of woof boots, which I like for cross country, especially when I am doing higher levels... sadly mine were stolen a few years ago. So I have the first link I posted and I have no complaints about them at all. I use them on both horses every single day and when I compete and they still look like new two years later.
