I bought 2 of these coats for my sons Whippets. Usually I have bought them Whippet shaped coats, as their body shape goes a lot thinner at the back than most dogs. These coats are the best ones I have ever bought. they are very warm and comfortable for them to ware. They fit their shape really well as the strap to do them up, goes through the front legs, and wraps around their bodies, and it tucks the side of the coats right under their bodies, which being a lot thinner than everywhere else, it keeps them really warm. The other type of coats do not protect the underside of their bellies like these coats do. The fleece is quite thick and plush, it's a really well made coat. For all those Whippet loveres buy your dog the best coat ever. It also has a big turn back collar, which when pulled forward protects their long necks, which the other coats don't as they are too short. This is great. I also bought them a snood for their necks , with a little elastic put in the one end , they are fully protected from all weathers. They look really smart walking together. You can tell we love our pets.
