I was thinking about giving my horse pro bias. It does not say horses can have it though. I though I heard people say they give it to their horses. My horse is not eating her timothy grass hay but is eating the flake of alfalfa I put out. I was wondering if she is spoiled and holding out or if there is a reason she is not eating the grass hay? She did not eat the grass last night or this am so I did not put anymore grass out but I did put the flake of alfalfa each time. I usually do one of each am and pm. She has been eating both kinds of hay for a couple months now and no problems. Also she was just wormed at the beginning of this month. Thank you!
