How do I correctly measure the neck Size of a dog?

PLEASE ALWAYS MEASURE DIRECTLY ON THE DOG'S NECK AND NOT ON THE COLLAR!

1. Chest circumference: Place the measuring tape at the widest part of the chest. Place 3 to 4 fingers between the armpit and the measuring tape so that the Biothane doesn't press anywhere later.

2. Back bar: Measure from the middle of the shoulder blades to the point where you measured the chest circumference earlier,

3. Shoulder circumference: Measure from the breastbone (lies in the middle of the chest and can be easily felt) to the middle of the shoulder blades.

4. Lower strap: Measure from the breastbone to the point where you measured your chest.
