A rug (UK), blanket (equine and other livestock, US), or coat (canine and other companion animals, US) is a covering or garment made by humans to protect their pets from the elements, as in a horse rug or dog coat.
Rugs are also used to protect the pelage of show animals, particularly if the wool or fleece is to be judged, as in alpaca fleece sent to an agricultural show, where it would be desirable to have the wool free from dirt and debris. Small dogs and dogs with thin pelage often need protection from extreme weather.[1][2][3]
