I'm struggling to find any possible reason for this. He lives out but currently wearing a 200g rug. Most people, with the exception of the people at the yard I've sort broached the subject to, are horrified to hear this. He does get fluffy & can get sweaty when ridden but surely now the nights are getting cold, even with a heavyweight (350-370g) combo rug for when it get's snowy etc., he'll notice ?
He's growing his coat back & his neck is quite fluffy now but I've been told he's due to be clipped again - not sure when though.
How can I best approach this without upsetting anyone, I only have the pony's best interest at heart. I cannot bear to think of him being cold & miserable.
(PS We have him on a part loan arrangement kept at his current yard)
