Considerations and Exceptions
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.
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.
