We know sizing can be a bit of a puzzle, especially when your dog’s girth measurement overlaps two size ranges. This guide is designed to help you choose the best size for a secure, comfortable fit.

Start with the Girth

The Balance Harness® is sized based on your dog’s girth, measured around the widest part of their chest, about 2–3 inches behind the front legs.

• Use a soft measuring tape or a piece of string and a ruler for accuracy.

• Compare your measurement to our Balance Harness® Sizing Chart or Reflective Balance Harness® Sizing Chart.

These charts are also linked on every Balance Harness® product page.

Choosing Between Sizes

When your dog falls between two sizes, the key is to pick the size that allows for the most adjustability, ideally, where your dog lands in the middle of the harness’s adjustment range, rather than at the tightest or loosest end.

If your dog is fully grown:

• If their girth is in the top inch of a size range, size up to ensure a comfortable, flexible fit with room for movement.

• If their girth is in the bottom inch of a size range, size down to avoid a loose or gapping fit.

• A centered fit within the adjustment range gives the best combination of comfort, control, and security.

Example: 24-inch Girth

Let’s say your dog’s chest measures 24 inches around:

• Small size expands to a maximum of about 25.5 inches. That fit would be snug with minimal room to adjust.

• Medium size tightens down to roughly 21 inches, making 24 inches a mid-range fit—ideal for comfort and customizability.

• Medium/Large would likely be too loose unless your dog is significantly larger in other areas, such as broader shoulders or heavier weight.

Tip for Larger Dogs or Strong Pullers

For dogs over 50 pounds or those who tend to pull on leash, we often recommend the Medium/Large size. The wider webbing helps distribute pressure more evenly, offering greater comfort during walks or training sessions.

We’re here for you. You can read our full guide on How to Size and Fit Your Balance Harness®, or reach out to our Customer Service team, [email protected] with any questions. We’re always happy to help you find the best fit for your dog.

We size the Balance Harness® based on your dog’s girth measurement — that's the measurement around the widest part of their rib cage — for a more personalized and accurate fit.

How to Measure:

• Measure 2–3 inches behind your dog’s front legs (around the widest part of their chest).
• Compare your measurement to our Balance Harness® Sizing Chart.
• Or our Reflective Balance Harness Sizing Chart

If you had trouble finding it earlier, don’t worry — you can always find the sizing chart linked here and on every Balance Harness® product page.

Choosing Between Sizes:

• If your dog is still growing (under 2 years old): Choose the larger size to allow room for growth.
• If your dog is fully grown: Select the size that offers the most room for adjustment for the best custom fit.

Example:
If your dog’s girth is 24 inches:

• A Small size allows just 1.5" of expansion (could be tight).
• A Medium size can tighten 3" smaller — offering a better adjustable range.
• A Medium/Large may be too loose unless your dog is much bigger.

Quick Tip:
For dogs over 50lbs or strong pullers, we recommend the Medium/Large — the wider webbing distributes pressure more comfortably.

Puppy Sizing Advice:

• Puppies 8–12lbs at pick-up usually fit into an Extra Small.
• Puppies 12–25lbs usually start in a Small.
• Expect your puppy to outgrow their first harness — that’s normal! Most pups transition from their first harness straight into their lifetime fit (often skipping a size).

How should the Balance Harness® fit my dog, and how can I adjust it for the best fit?

The Balance Harness® is designed to fit like a comfortable “necklace” across your dog’s chest — lower than a traditional collar — to avoid pressure on the trachea and to allow natural movement.

How to Check Your Dog’s Balance Harness Fit:

• The neck loop should sit lower on the neck, not high like a collar.
• The girth (belly) strap should sit at least 2 inches behind the front legs to prevent rubbing or chafing. However, you don’t want the girth strap placed behind the rib cage — it should wrap around the widest part of the rib cage for the most secure and comfortable fit.
• Allow a little slack in the chest strap (the strap that goes between the front legs) so your dog can comfortably look upward without feeling restricted.
• If the harness shifts forward when your dog moves, loosen the chest strap slightly to allow for better range of motion.
• Some side shifting is normal during walks — this ensures full shoulder freedom.
• If the harness twists or moves too much, use a double-ended leash (like our Multi-Function Leash) to balance leash pressure from both the front and back attachment points.

Additional Fit Checklist:

• Is the front leash attachment point resting near the bony part of your dog's chest?
  If it’s too high, it may cause coughing when your dog pulls. If it’s too low, the neck loop may rotate excessively.
• Is the girth strap fitted around the ribcage?
  If it's too far forward, it can cause chafing in the armpits. If it's too far back, it may press on the softer part of your dog’s belly or abdomen.
• Does your dog appear comfortable?
  If your dog immediately tries to chew at the straps, bites at the harness during walks, or refuses to move, these are signs that the harness may need adjustment.
• Do you feel in control of your dog?
  Be sure the girth strap is snug enough that your dog can’t slip out during walks.

Pro Tip:
Our straps are made of durable, high-quality nylon that may feel stiff at first but will soften quickly with regular use.

You will be happy to know our KLIMB is built to last. It has a weight rating of 500 lbs, is made of composite material, and UV stabilized to last a lifetime outdoors. The KLIMB is durable, lasting, and easy to clean!  

For more information visit Blue-9 KLIMB

Due to the nature of the composite material that the KLIMB is made out of, changes in temperature and humidity can cause the KLIMB tabletop to expand and contract.

We specifically formulated this composite material to be durable while still allowing a bit of give for the comfort and safety of the dogs jumping on and off of it. Our composite has a rubberized component that gives dogs extra grip when jumping on and off of the KLIMB, as well as a cushion to absorb the concussive impact of repetitive jumps. Also added is a UV stabilizer to prevent the KLIMB from deteriorating when left in the sun.

If you wish to preserve the ability to disassemble and transport the KLIMB, we recommend the following:

• When installing the KLIMB legs, give them an extra twist with BOTH hands. You cannot strip the screw component or overtighten it. This video is very helpful to learn more about how to make adjustments to your KLIMB: KLIMB Dog Training Platform Benefits and Uses
• Avoid dragging or tossing the KLIMB when moving it from one location to another.
• In some cases, a small strip of electrical tape placed along the "threads" of the legs can provide extra grip.

Blue-9 recently found a solution to this challenge and have come out with new upgraded KLIMB Legs that will not loosen with use. You can purchase the upgraded replacement legs that will work with any KLIMB here: KLIMB Replacement Legs - Set of 4 – Blue-9 Pet Products.

This video shows you how to train your dog to go to the KLIMB and stay there, even during distracting situations such as when a guest rings your doorbell.

We know dogs chew EVERYTHING, especially new or novel items like a shiny new harness. Our premium soft-touch nylon has a 3500lb test strength. You could tow a small vehicle with it! Our nylon doesn’t rip or fray when worn by a dog. It doesn’t matter how big or strong, or how much you use it, it does not fray on its own.

We know it can take less than 5 seconds for a dog to rip into a strap when left unattended. Note: The same is true for KEVLAR webbing, the same material that stops bullets for our uniformed officers is still no match for our dog’s strong teeth and jaws, designed to snap through animal bones with ease.

In each package with our Balance Harness, we include Chew Prevention Tips. We also offer a one-time 90-day Chew Warranty. Your harness is most at risk of chew damage during the first month or so that your dog is wearing the harness. As they get used to the new sensation, we recommend watching them like a hawk during this time period to prevent chew damage.

We’ve got you covered though if they manage to sneak in a few chews! In the event your dog chews on the harness rendering it unusable, we’d like to provide a chew warranty offer. Our one-time chew warranty offer is available if your puppy manages to chew/damage the harness within the first 90 days of purchase. Our offer provides you 50% off your replacement harness. 

For more information, please contact Customer Service and let us know your order number with a brief explanation of what happened and include a few photos of the damaged Balance Harness for us to see.

If you did not purchase your Balance Harness directly from Blue-9, also include confirmation of purchase along with the photos requested.  

The Balance Harness was designed to give you more leverage over your dog while you work to train your dog not to pull, while still providing them with free range of motion in the forelimb. 

By nature, all front-clip attachment harnesses will turn towards the direction that leash pressure is coming from. This is the harness doing its job, what we have to do is stop walking forward for a moment and allow the dog to turn back towards us before we continue to walk forward. 

The Balance Harness will give you more control over your dog when compared to walking them on a flat collar. We recommend using a double-ended leash like our Multi-Function Leash for the most control and influence while training your dog to walk nicely on leash.

The Multi-Function Leash certainly helps with super-strong pullers. If the double attachment function isn't working the way you'd like, you can certainly use it as a regular 6-foot leash or hold on to it until your pup is a loose leash walking pro, at which time you can even use it as an over the shoulder leash on your public outings. 

Check out our Loose Leash Walking playlist that will give you 5 short and easy-to-follow videos to train your dog using the Balance Harness.

When it comes to keeping your Balance Harness spick and span, we've got some friendly tips to ensure it stays in top-notch condition for your furry companion.

1. Choose the Right Cleaning Agents: For the paw-fect results, opt for dog shampoo or a mild dish or laundry soap that's safe for your doggo. Keeping it dog-friendly is the way to go!

2. Machine Washing Method: If you prefer using a washing machine, don't forget to buckle all the harness buckles together first. Pop it into a garment bag and select the gentle cycle wash setting. Your harness will thank you for the gentle treatment!

3. Handwashing Hack: For those who prefer the hands-on approach, start by soaking the harness in sudsy water. Gently scrub the nylon with a soft brush to get it squeaky clean.

4. Air Dry All the Way: No matter which cleaning method you choose, always air dry your harness. It's the secret to keeping it in tip-top shape!

5. Any Questions?: If you have any more queries or need further assistance, don't hesitate to reach out to us. We're here to help with wagging tails and open hearts!
