I went through the reviews and bought the medium one because Large seemed to large. I have a Schipperke with about 8/9Kg and it fits well with enough room to stay with his head out of the backpack. He loved.
I ordered two mats at risk at once, by the number of cats and did not regret it! The fabric is quickly cooled, but how exactly the animal will not heat it up when used-it is not yet clear) in any case, I do not regret buying The litter consists of three layers: 1) texture like the cooling sports towel 2) sintepon (apparently for softness and temperature retention) 3) surface with circles, pleasant to the touch and cool Sizes for S correspond to the description Seller recommend! Sent the goods quickly, the goods tracked to the very arrival
I bought my children a dog, and they are just delighted! I can't let her go. Plus and I'm glad of such a thing) very cool. I'll order another one.
