fiona9 - It seems to me that such things are sold in ordinary pet stores.

kenny6 - Could you tell me, have you looked at the warm jacket for dogs on this site https://waudog.com/products/airyvest-dog-jacket? I'm just sure that you'll choose one of the jackets which are sold on this site because they are amazing. They are made of a very soft and lightweight material that doesn't hinder your dog's movements. The jacket also has a waterproof layer, so your dog can safely walk in the rain. You're welcome.
