*Always choose your size according to the latest measurement of your pup. We suggest rounding up to the next size if your measurement is near or over the maximum range, if your pup has a broad chest or thick coat or if you are in between sizes. If your pup usually wears size Small, this does not mean all size Smalls will fit the same as designers use their own sizing.
