Chest/Girth: Measure girth around the broadest part of the chest.(CHEST GIRTH data is the most important data for purchasing this raincoat!) Your baby usually wears size S doesn't mean all size S will fit him/her. Always look at the size chart for chest girth and length and confirm the size before you commit to buy. Take each measurement a bit loosely, so there will be room for your dog to move and breathe, but not too loose.
