I'm a dog home boarder and one of the Greyhounds who stays with me wears Pjs at night, pretty typical with really short haired breeds

 

Yes, I have a pair of fleece PJs for Maisy because she chills easily in the winter and they keep her buns toasty.

 

People like them because it keeps the dirt on the dog instead of your bed.

 

My dogs wear pajamas all winter long, if they didn't they'd freeze. They also have an assortment of coats, too.

These pajamas my MIL and I made, we got the pattern at JoAnn's.

 

Those look awesome! My daughter always picks out adorable dog outfits at the pet store and asks if we can get them for Jasmine, I always have to say no, as she has thick warm fur and is fine outside in pretty much any weather (it is usually the humans who get cold first!) I sometimes wish I had a single coated or small dog when I see those adorable outfits!
