I got a 2 year old filly I don't want her to learn to much so it blows her brains but I just feel she's getting bored and needs to learn or do new things. What would you guys recommend doing please
Normally boredom breakers are company/turn out/food. Anything else is a bit 'extra' from a horse perspective.
Other with more experience of youngster will have ideas as to what you might want her to learn, but I'd suggest that is different from boredom prevention per se.
