IMPORTANT INFO: Avoid Horizontal Strap Harnesses

Many owners don’t realise that not all harnesses are designed with their dog’s comfort and movement in mind. Some popular styles — especially those with a horizontal chest strap — can actually restrict shoulder movement and lead to long-term issues. Let’s take a closer look at why the wrong dog harness could be doing more harm than good, and which ones are better for your dog’s body.

Why Chest Strap Harnesses Restrict Movement

Okay, so here’s the deal: those popular horizontal strap harnesses (looking at you, Julius K9) might be doing more harm than good. That innocent-looking strap across the chest? It’s basically putting your dog in a full-body hug that restricts shoulder movement and could lead to serious joint and mobility issues.

A Julius K9-style harness places a restrictive strap across the shoulders, limiting natural movement.

Imagine someone strapping a belt around your chest and shoulders and then telling you to go about your day. “Sure, just swing your arms like normal. No big deal!” You’d look like a robot attempting jazz hands. Awkward.

Now picture that same scenario for your dog — except they’re trying to run, play, or even just walk without feeling like they’re in some kind of canine straitjacket.

Harness Myth: “Harnesses Teach Dogs to Pull”

While we’re busting myths — no, harnesses do not teach dogs to pull. That’s an old training tale! If you’re curious, check out our quick guide that explains the science behind it: Watch Here.

It’s like the Rolls-Royce of harnesses: comfy fit, top-notch quality, and total freedom of movement. If dogs could talk, they’d say, “Yeah, this is the one.”

Important: Use a Crash-Tested Car Harness

A quick safety reminder: never use your walking harness in the car. Instead, always use a Crash-Tested Harness that’s designed to protect your dog in case of sudden stops or accidents. Many owners don’t realise that most harnesses are not tested for crashes — so it’s well worth the switch.
