Neck – Measure the neck length as you would for a collar. Allow some leeway for a comfortable fit. Chest - Measure around the chest at its widest point, which is typically right behind the front legs. Allow some leeway for a comfortable fit. Body Length - Measure along the dog's backbone from the base of the head to the base of the tail. This is from the base where the collar rests to where the tail is attached. If neck, chest and body length measurements are listed on the size chart for an item, take into account all measurements and choose the item that best encompasses all measurements. |
