To ensure the proper fit, please measure your dog accurately by following these instructions:

Dog Collars
Measure around the neck close to the shoulder and allow 2 fingers for room, for a comfortable fit. If your dogs measurements are near or in between two different sized collars, order the next size up to allow for growth and/or a comfortable fit.

Clothing
Measure from the base of the neck (where a collar would rest) to the base of the tail.

Harnesses
Measure around the largest part of the chest which is usually behind the front legs.
