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

1. Total weight

Knowing your dogs total weight gets us in the ballpark! So first and foremost, know their weight!

2. Torso

Each breed typically has a unique body shape with variations within. Deep chest, narrow waist, shallow chest, tubular, skinny and of course plump or overweight. We know our dogs well so this should be easy.

3. Legs

A dog’s legs can make up a quarter of their total body weight! Are your dogs legs short or long, stout or skinny? Legs tell us a lot.

4. Range within a size.

Each of our harnesses has 11 separate adjustments. This is so you can adjust to meet the unique characteristics of your dog. 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! This also means there are about five pounds of crossover at the top and bottom of each size. Ask for help if you are unsure.

4. 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.

5. 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. We sell separate fronts and backs on our accessory page and all sizes
will connect easily front to back as separates.

6. Selecting the correct Hip Lift.

As a last note on sizing we make 2 versions of the Hip Lift, the Conventional and 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. We go into greater detail on selection on our Choosing the Correct Hip Lift page.

7. “Out of the Bag”.

Right out of the bag all of our harnesses come fully assembled, meaning the the front and 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.
