Is ideal,except for the material. The fabric is entirely synthetic, very fine and fresh. Even so, once the dog wears the pajamas, it heats up. It is to put it at night inside the house; It does not serve to shelter them outside. The design, the elastics and the trenches very well. As the leg is not tight, my dog walks and runs without problem with him. I was worried about the size but the pajamas are somewhat elastic and it is very large. My dog's back length is 35cm. That yes; It goes back a little so I will have to give it a few stitches to sew the back and that it does not drain and cover the cut.
