Is your dog's harness hurting them?

A poorly fitted harness causes long-term joint damage. Learn how to protect their movement on every trail.

The invisible collarbone

Dogs don't have collarbones. Their legs attach via muscle alone. Pressure on the shoulder blades isn't just uncomfortable—it's structural interference.

2 / 10

T-Bars vs. The Y-Shape

Horizontal "T-bars" block the natural rotation of the scapula. Look for the Y-shape instead. It leaves joints free to move through a full range of motion.

3 / 10

Measuring the base of the neck

Forget the collar line. Measure where the neck meets the shoulders in centimetres. Too high, and you're putting pressure on the trachea.

4 / 10

The "Armpit Gap" rule

Never let the girth strap sit in the armpit. Leave about 4cm of space to prevent painful friction and skin irritation during long treks.

5 / 10

Locate the sternum

The harness must center on the breastbone. If it's resting on soft throat tissue, your dog is losing power and comfort on the walk.

6 / 10

The Two-Finger Rule

Two fingers should slide flat between the strap and your dog's skin. No more, no less. This prevents the "slip and chafe" effect.

7 / 10

Test the dynamic fit

A harness that looks good standing might shift when they trot. Watch from above—is it staying centered on their spine as they move?

8 / 10

The Canadian Winter Trap

Bulky parkas change the fit entirely. Re-adjust your harness every time you add or remove a layer. One size doesn't fit all seasons.

9 / 10

Stop the "Back-Out" escape

Sighthounds and escape artists need a three-strap harness around the narrow waist. Don't rely on neck tension for security.

10 / 10

Watch for the "Piston" walk

Front legs should move straight like pistons. If they're swinging wide, the chest strap is blocking their reach and hurting their stride.

It isn't just gear. It's health.

A harness isn't for control; it's a tool for skeletal freedom. When the fit is right, their gait is effortless and their joints are protected.
