If you’ve seen my dogs Mabel and Murphy in photos or on walks, you’ll know they’ve been modelling their Perfect Fit harnesses for years. As a canine counsellor, I’m often asked why I prefer harnesses over collars. The answer? Comfort, safety, and control without compromising movement or wellbeing.
The Science Behind the Switch
Research shows that collars, especially when used on dogs that pull, can put pressure on the trachea and cervical spine. This can lead to discomfort, coughing, or even long-term injury. A 2025 review in MDPI’s Animals journal found that non-tightening front-clip harnesses offer a safer alternative, distributing pressure more evenly and reducing stress-related behaviours.
Another study in Frontiers in Veterinary Science observed that dogs wearing harnesses showed more engagement and fewer signs of stress compared to those in collars, even when pulling towards food rewards.
And while some harness designs can restrict shoulder movement, well-fitted Y-shaped harnesses like the Perfect Fit are designed to avoid that, allowing dogs to move naturally and comfortably.
Control Without Compromise
I often recommend using a double-ended lead, one clip on the back of the harness, one on the front. It gives me smoother control and clearer communication, especially when working on heelwork or managing excitement.
It’s not about forcing compliance; it’s about calmly guiding with clarity.
But Will It Stop Pulling?
Here’s the truth: a harness won’t magically stop a dog from pulling. That’s where training comes in. Teaching loose lead walking is a skill that takes time, consistency, and the right reinforcement. The harness is a tool, not a solution. But it’s a tool that supports your dog’s body and your training goals.
Final Thoughts
Harnesses like the Perfect Fit are more than just gear; they’re part of a thoughtful approach to dog handling. They protect your dog’s physical health, support natural movement, and give you the control you need to train effectively. Mabel and Murphy are living proof: happy, healthy, and beautifully behaved.
Note: I’m not affiliated with Perfect Fit in any way. It’s just my preference!
