How to Measure Your Dog



  1. Neck: Measure the circumference of the base, leaving enough space to fit two fingers comfortably.
  2. Lower Neck: Measure the circumference of the area above the shoulder blades towards the top of the chest, leaving enough space to fit two fingers comfortably.
  3. Chest Girth: Measure the circumference of the widest part of the chest behind the front legs.
  4. Length: Measure the length of your dog's back from the top of their shoulders to the base of their tail.
  5. Height: Measure the distance from the floor to the top of your dog's shoulder blades. Your dog needs to be standing on all four legs.
  6. Paw Width: Measure the widest part of the paw. You'll get a better measurement if your pup is standing.
  7. Paw Length: Measure the distance between the "heel" and the longest toe nail. You'll get a better measurement if your pup is standing.
  8. Muzzle Length: Measure the nose length from the tip to the crook where you want the muzzle to sit comfortably below the eyes.
  9. Muzzle Width: Measure the muzzle's circumference at the widest part, leaving space for two fingers to ensure a comfortable fit.
  10. Weight: Step on a scale while holding the dog, then subtract your weight from the total. A dog scale is conveniently located at all our locations.
