1. NECK CIRCUMFERENCE
For your dog's neck circumference, measure the circumference from the tip of the sternum over the shoulder blades. Remember that the neck circumference of the harness does not correspond to the neck circumference of the collar, as the harness is further back.
2. Belly Circumference
For the belly circumference, measure the circumference behind the front legs. For large dogs, you can place the measuring tape about a hand's width behind and for small dogs two to three fingers.
3. Belly Bridge
Measure the breast ridge from the tip of the sternum to just behind the front paws, from the neck circumference to the belly circumference.
4. BACK Bridge
The back bridge is measured between the shoulder blades from the neck circumference to the abdominal circumference.
