our furry friends come in a variety of shapes and sizes, if your pup falls in between a size bracket we suggest going up for a comfortable fit. the chest/girth measurement will usually determine the best fit for your pup, however every pup is unique so we recommend following the chart below with measuring tape to ensure sizing is accurate.

every product has a 'Size Chart' tab where you will find the measurements available for that product. below is a size/breed comparison chart for standard sizing, but keep in mind each product is unique and every pup is different.
