How to measure:

Neck: Measure right around the neck, allowing enough room to slide 2 fingers in for comfort
Length: Measure from the base of the neck (where the collar would sit) to the base of the tail along the dog's backbone.
Chest: Measure right around the body around the deepest part of your dog's chest, usually just behind the dog's front legs.
M&H Top Tip: If you do not have a suitable tape measure, use a piece of string (or similar) and measure this against a tape/ruler.
