I purchased this item, but unfortunately, it was too small and I couldn't use it. I apologize to the previous seller, but I am also putting it up for sale. It's made of a very soft and warm material. I haven't even tried it on my dog, but the previous seller said they used it twice outdoors when their puppy was young. Please understand that this is a used item. For reference, my Chihuahua is 1.9kg and slender, but it didn't fit. It might be for puppies.
