Ten years of sizing harnesses has taught us a few very important lessons. Here are the most relevant factors to consider.

  1. Total weight
    First and foremost, knowing your dogs total weight will help you determine what size harness you need. Go by the weight of your dog.
  2. Range within a size.
    Our harness is fully adjustable. You can adjust to meet the unique characteristics of your dog’s dimensions. Each harness has a broad range within its size definition. Meaning – you can adjust the chest to a deep chest or a shallow one, a narrow waist to a plump waist, our harnesses have range! If your dog is on the cusp of two different sizes, we recommend sizing down. Ask for help if you are unsure.
  3. Consider their age or their condition.
    Once a dog reaches a certain age (it’s different for all) they tend to stop adding on weight. So it’s best not to apply the “they’ll grow into it” method. If your dog is losing weight, project ahead. If your dog is recovering from any number of issues, surgery, injury etc… they might be up a few pounds. Once again the harness has added length to straps to accommodate changes.
  4. Mixing sizes.
    We get asked this a lot and its really why we have the broad range within each size. Occasionally, and with certain breeds it becomes necessary to “mix and match”. We sell separate fronts and backs on our accessory page and all sizes will connect easily front to back as separates. This comes in handy if your dog has atrophied in it’s hind quarters. You may need a large front and smaller rear Hip Lift. But remember, we go by the weight of the dog primarily to choose the correct size. Call if you are unsure.
  5. Selecting the correct Hip Lift.
    As a last note on sizing, we make 2 different styles of the rear Hip Lift: the Conventional or the “U” Band. All females and 80% of males will wear the Conventional version but those males whose penis sits further back, between their hind legs or just even with the front of the hind legs will use the “U” Band style. We go into greater detail on selection on our Choosing the Correct Hip Lift page.
  6. "Out of the Bag"
    Right out of the bag all of our harnesses come fully assembled, meaning the the front and rear Hip Lift are connected. Please note how it is assembled before taking it apart. It has 11 separate adjustments and 9 separate connector clips. Try it on your pup first as it is and then make adjustments. Please refer to our fitting demonstration videos for more help.

    Note: There are several places where more strap may be tucked into neoprene sleeves, make sure the straps are pulled out to get more length. You can scrunch the neo-sleeves down if you need to tighten the straps. They are soft and flexible.
