It was bit too small for a pekingnese girls
I bought 3 jackets, 2 in 30cm for 2 Pekingnese (5.2 - 5.5 kg) girls, and 1 in 40cm for a Lhasa apso mix girl (8.2kg with long coat). The 30 cm length was bit too short on the backs and bit too tight around the chest. The 40 cm is perfect for 8.2 kg long coat Lhasa apso. I bought them as a rain jacket in cold weather. The quality of jacket is good for the price and works as a rain jacket and keeps the body warm. The size 30 cm is exactly 30 cm on the back and it is bit too short for a Peke.
