That 'no-pull' promise could be causing permanent joint damage with every step.
Unlike you, a dog's front legs are held by muscle and tendons. When a harness blocks the shoulder blade, it restricts their entire skeleton.
Horizontal chest straps act like a brake. They physically block the forward motion of the humerus, leading to a shortened, painful gait.
A Y-shaped harness follows the natural skeletal frame. It leaves the shoulder joint open and the throat safe from pressure.
A 50lb Bulldog and a 50lb Greyhound have totally different frames. You need specific girth and neck-base measurements.
Forget the collar line. Measure where the neck meets the shoulders. This is the structural anchor for a healthy fit.
If the strap is too close to the front legs, it causes 'harness burn.' You need a 4-finger gap behind the elbow for a full stride.
Too loose causes friction; too tight restricts breath. You should snugly fit exactly two fingers under any strap at any time.
Does your dog freeze when the harness comes out? It’s likely pain or nerve pressure, not an attitude problem. Check the fit.
Deep-chested dogs can 'back out' of standard gear. A third safety strap behind the ribs makes escaping physically impossible.
Weight and coat thickness change. Re-verify your two-finger fit every single time you clip in for an adventure.
A perfect harness fit isn't about control—it's about biomechanics. Protecting their shoulders today prevents a lifetime of arthritis.
