Neck - Measure around your dog's neck at
the level where the collar would normally sit.
Make sure you can fit two extra fingers in,
so that the collar is not too restrictive.
Chest - Measure around your dog's chest directly behind the front legs, as shown in the diagram.
Note: This is the most important measurement for a coat, jacket, or sweater - If the chest measurement is wrong, the item will not fit.
Back - Measure your dog's back from the base of the neck to the base of the tail.
This will ensure that the garment sits in the right place and that it does not extend beyond the tail.
