It depends on the horses coat, now that i have own clippers i can clip whenever i want too. Before they got done wenever i could get hold of some clippers, so would clip october and january.
normally end of september, but im also contemplating sooner as my mare is moulting so bad!
But i know people who clip there fluffy ponys all year round, so it depends on what you plan to do with them and how hairy!
If your showing id advise not to!
Well my horse still has his summer coat with no signs of moulting at all. This will be his first year clipped and I have been recommended to leave it as long as possible and to just do him when he starts to sweat up with his winter coat coming through. So I am hoping it will be towards the end of Sept as I really want his winter coat to come through before rugging him!
I'll (very reluctantly) be clipping my young 'un pretty soon, even though she's just about to come into work after a tendon injury, her coat is a massive fluff ball and when her coat is all winter wooly she gets bad skin irritations. Bummer eh?
