Okay, so I have a little 12.2hh pony Bart. He just turned 20 this year and has always been on the skinny side while in our care because our vet told us he is at risk for cushings and he is prone to laminitus(sp?) and founder. Well, I have always been okay with barely being able to see his ribs when he breathes out but I've been noticing lately how out of control this has gotten. We have my grandparent's wild burro, not so wild anymore but wild enough to where he wont get in the trailer and go home, and he keeps stealing Bart and Dozer's food! Dozer isnt underweight and I don't know why he isnt! He pushes his food out of his stall if I don't feed Radar to try and share. Oh! I forgot to mention, Radar is VERY obese and I want to get that down but I can't control what he eats because he isnt mine... Anyways, yesterday my grandparents told me to not feed him, well, that isnt good on him mentally and even if I don't feed him he just steals Bart and Dozer's food. I can't lock him up because they would get really mad at me because last time he was locked in his eye got scratched by something. But if I don't lock him up he can get whatever food he wants...
Any advice would be greatly appreciated because I WONT let my pony get any thinner.
