*Measuring Your Dog for a Perfect Fit* Your baby usually wears size S doesn't mean all size S will fit him/her, please check the size information carefully before buying. You looked at one size chart and found that your dog is a size small. But that doesn't mean he/she is a size small for all the clothes. Different designers and manufacturers use their own size charts. So the measurements given in a size SMALL by manufacturer A will be a size XS in manufacturer B's size chart. Don't buy a particular size because that is what you always buy in a pet shop or online store. Always look at the size chart for chest girth and length and confirm the size before you commit to buy.
