Um-
The definition I know for “windsucking” only applies to MARES. And only when they are galloping.
Do you mean he is cribbing?[/QUOTE]
there is cribbing, windsucking and mare windsucking.
Get him outside, when he has to be in a stall NO hanging buckets, give him ground feeders and a rubbermaid tub or other safe container on the ground for water…just make everything too low to suck on and give him all the hay he will eat. Lots of exercise and routine usually help too. OOppps just saw your post he lives outside…try exercise and a nice daily ritual, I find if I massaged my guy he would keep his mouth off stuff for a little while after. I really believe it boils down to their brain chemistry and anything else that may get the happy juice flowing might help reduce the wind sucking.
