Yes, most whippets, greyhounds and smooth lurchers are wearing coats now, a fleece coat is perfect for this weather, fleece pjs for when it's really cold and you'll probably find he won't want to go out in the wet, but if you insist then yes a waterproof coat too would be most welcome :-)
I bought one of
these for a friends whippet at Christmas and it's fabulous, really thick and good quality and covers her up completely, this would be for very cold days.
These are great waterproof coats.
If you search online you will come up with lots of lurcher/greyhound/whippet coats, don't buy any normal dog shape ones because they're just not deep enough in the chest and are always too baggy at the waist.
My old lurcher loved these fleece
jumpers, available in a variety of understated
colours. She hated getting her jumper off, and would stand and stare at it on the radiator, willing it to jump on her :-)
