this is one of those topics that can carry on forever. My experience with horse bedding is the best I've used is kiln dried pine shavings, thin shavings mixed with sawdust. It's more absorbent, less dust. Most your sawdust only beddings come from mills that dump into your trailer just after it was cut from a log, which means wet or damp. Hardwood shavings suck in my opininon. I just picked up a dump trailer load of poplar, mixed with other hardwoods. Worst absorbing bedding I've used. Most pallets are made of oak, so won't be as absorbing as pine or cedar. Going rate for thin pine shavings here is 30 dollars a ton, not bad in my opinions. I have 4 paso finos and 2 clydesdales, and seems to work the best even with the heavy peeing clydes
