This is a repost(ish) but well worth repeating. Many of you have heard me harp on harness fit time and again. Having spent decades evaluating harness fit in working dogs of all types with thermal imaging (as well as having years of working and active dog experience combined with a strong biomechanics knowledge base) using front-clipping or "Gentle Leader" type harnesses only guarantee more structural stress in active dogs that makes for more work for me and other chiro/sports med colleagues. PLEASE only use harnesses that fit with proper ergonomics! [NOTE: I've tweaked the English & syntax in the added-on description below so it might read a little differently.]
"All dog owners should know this fact! A harness like this is a terrible injustice to your pet!! AVOID USING THIS TYPE OF HARNESS !
In a dog's forward movement, a harness with a tape that crosses its chest from side to side hinders it in the same way humans would bother going hiking with an elastic band holding their arms. Physiological movement of the front extremity is prohibited. Just like rubber would inhibit the pendular movement of our ARMS.
Thanks to the "Study of Canine Movement at the University of Jena", we now know that in the dog, the center of rotation of the front limb is at the top of the scapula, but in the human the center of rotation in the arm is in the shoulder (head of the humerus). Jena's study demonstrates, among other things, the importance of scapular movement for dog locomotion. Now we understand the importance of taking into account the free movement of the dog's shoulder when choosing a chest harness.
That means there SHOULDN'T be bands across the scapular (orange) area, and they shouldn't cross the chest side to side either.
From the point of view of biomechanics and physiotherapy, it is recommended not to choose getting harnesses that have a strap that goes through the chest laterally, or that have straps that touch or press the scapula.
Always lean towards harness models with ERGONOMIC design, to allow maximum freedom of movement for your dog, improve his well-being and safety during his walk.
