Total Weight

In most cases, your dog’s total weight will determine what size they need.
Tip: If your dog’s weight is between sizes, we recommend sizing down.

Age/Condition

For older dogs that may be struggling with atrophy or degenerative hind quarters, sizing down the harness rear may be needed to achieve an optimal fit. Please explore our Mix & Match option.

Tip: Consider where your dog’s total weight falls within a size range. If your dog weighs at the lower end, a smaller rear harness might help—a 55lb dog with a degenerative hind may benefit from a small size rear, while a 75lb dog with similar build would do well with a full medium.

Breed

Occasionally, some barrel-chested breeds may require a larger harness front in order to achieve an optimal fit. If your barrel-chested dog’s total weight is between sizes, consider our Mix & Match option—size up the front and size down the rear.

Does my Male Dog need a U-Band?

Note: Not available in size XS

For 20% of male dogs, the tip of the penis starts further back between their hind legs. The U-Band provides clearance for male dogs who may be hindered from urinating by the conventional version.

If the tip of your dog’s penis is not visible from a side view (see diagram), a U-Band is recommended. Please contact us if you are unsure or require assistance.
