My mare, who has been done shedding for almost a month and a half, is in the same field as an older QH. He's shedded out fully, except for his barrel. The hair is obviously dead because it's blonde, and he's black.
He gets his normal grain, senior grain, hay pellets, and hay. All twice a day. They've also been out on grass quite a bit this year.
Do you have a shedding rake? I use a sleekez, and it's super awesome. When that horse comes out, I always go over and start shedding him out. It's not coming out in clumps, but it is coming out. SleekEZ — Welcome
If you have a dog/cat/smaller animal, it's cheaper to get the pack of them. You could look around elsewhere as well. You could probably find them cheaper.
