Do Thoroughbreds Need Winter Covers?

As you guys already know I am the owner of two wonderful thoroughbred mares (Chancy and Specere).
Now a lot of people think that thoroughbreds need winter rugs due to them having thinner skin than normal horses... Well the truth is, that thoroughbreds don't..

Now ever since Spec's was a filly she had been wearing rugs and living in a stables. Because of all this pampering from an young age this has altered her into needing a rug in winter because she depends on it.

Hay is a very good ruffage to give your horse in winter. It helps keep them warm!

But Chancy never has worn a rug or been stabled and she has a thick coat and is happily living without getting cold! I didn't muck around with chancy so she is less prone to getting cold!

I hope this helps thought I better do a quick post :P
