  • First things first. Make sure you know your dog's measurements
  • GIRTH - Measure around the widest part of the dog's chest
  • LENGTH - Measure from the collar to the base of the tail
  • If your measurements don't line up perfectly with one size or have a growing dog, don't worry. Select the size that accommodates your largest measurement. You can always add a Booster Block to make up for lack of length.
