Most harnesses restrict the shoulder blades, causing long-term joint damage. See if your gear is safe.
Dogs don't have collarbones. Their shoulder blades slide on muscle. One wrong strap acts like a bicycle brake on their natural movement.
Horizontal chest straps are popular, but they block the 'point of shoulder'. This forces a shortened, painful gait over time.
From the front, your harness should form a 'Y'. This channels pressure onto the breastbone, leaving the joints completely free.
If the 'Y' sits too high, it hits the trachea. If your dog coughs or wheezes, the harness is just a collar in disguise.
Don't guess the size. Measure the girth 2-3 finger-widths behind the front legs. Too close, and you'll cause painful armpit chafing.
You must be able to slide two fingers flat under any strap. Too loose? It chafes. Too tight? It restricts their breathing.
A fit that looks good standing might fail while sniffing. If the 'V' shifts when they put their head down, it's the wrong shape.
Greyhounds and Whippets have deep chests and narrow necks. They need a 'three-strap' design to prevent backing out of the gear.
Is your dog 'gear shy'? If they hide when the harness comes out, they are telling you it hurts. Check for hot spots and fur loss.
Observe them trotting. Front paws should land under the nose. If they 'shuffle' or look stiff, the harness is stealing their stride.
A harness isn't a fashion choice; it is a biomechanical tool. Respect the shoulder blades, and you protect their joints for life.
