| In short : The choice between the collar and the harness is the subject of much debate among dog owners. If the collar remains the traditional accessory, the anatomical and biomechanical analysis carried out by canine osteopaths leans more and more in favor of the harness, while bringing crucial nuances to it. Here are the main findings of animal health professionals: – The collar and cervical risks: Repeated tractions or bells on a collar exert violent pressure on the throat and cervical vertebrae, which can lead to blockages, muscle tension, or even respiratory or thyroid pathologies. – The harness to preserve the column: A suitable harness distributes the traction force over the rib cage (a much more robust area than the neck) and releases the dog’s airways. – Beware of the shape of the harness (the harness trap in T): Not all harnesses are created equal. Osteopaths warn against so-called “T” or Norwegian harnesses that block the shoulder and block the natural movement of the joint. – The Y-shape, the absolute recommendation: The ideal harness must completely clear the shoulders and neck, drawing a “Y” on the dog’s chest to respect its biomechanics. |
When you walk your dog, the tension on the leash is sometimes inevitable. Whether it is a young dog in full learning to walk on a leash, a sudden gap to pursue a bird, or continuous traction, these physical forces are directly absorbed by the animal’s body.
Where the veterinarian treats visible pathologies, canine losteopath analyzes the repercussions of these forces on the musculoskeletal system. And their finding is clear: the choice of walking equipment has a direct impact on the posture, freedom of movement and joint aging of your companion.
1. The collar under the eye of Losteopath: an ultra-sensitive area
The dog’s neck is home to vital and extremely fragile structures that are not protected by a solid bone frame.
The anatomical impacts of the tractions on the collar
When a dog pulls on its collar, the local pressure compresses major anatomical elements:
- The cervical vertebrae: Repeated tensions can create vertebral micro-displacements (subluxations), chronic muscle contractures in the neck and, in the long term, promote the appearance of a herniated disc.
- The trachea and the larynx: Mechanical compression is the cause of irritation of the throat (the famous cough reflex when the dog pulls). Ultimately, this can aggravate a slumping of the trachea, particularly in small breeds.
- the thyroid gland and circulation: Located at the base of the neck, the thyroid can undergo repeated mechanical trauma, leading to inflammation. In addition, the pressure increases the eye and venous pressure of the head.
The osteopathic point of view: The collar should only be used in dogs with a perfect leash walk without any traction, or simply to wear the identification medal. As soon as there is tension, the risk of postural compensation (the dog modifies its gait to escape the pain) is high.
2. The harness under the eye of Losteopath: distribution and restrictions
The harness is the ideal solution for relieving the neck, as it moves pressure points to the rib cage, designed to dampen shocks. However, osteopaths warn about the harness morphology.
Horizontal harnesses (in “T” or Norwegian): Avoid for walking
These harnesses have a wide horizontal strap that bars the dog’s chest from shoulder to shoulder.
- The negative impact: This strap directly compresses the scapulo-humeral joint (the shoulder). At each step, the extension of the front leg is blocked by the fabric. To compensate, the dog is forced to modify his gait, which creates major muscle tension in the back and shoulder blades, promoting early wear of the cartilages (osteoarthritis).
Harnesses in “Y” or “H”: the recommendation of professionals
These models have straps that pass between the front legs and rise on each side of the neck, completely releasing the tip of the shoulder.
- Positive impact: The contact point is located on the sternum (solid bone). The shoulder can move back and forward without any textile constraint. The freedom of movement is total, respecting the dog’s natural biomechanics.
Summary table: anatomical comparative collar vs harness
| Criterion of evaluation | Necklace | The T-harness (Norwegian) | The Y-harness |
| pressure zone | Neck (trachea, cervical, thyroid) | Shoulders and sternum | Sternum and rib cage |
| Respect for the shoulder | Excellent (totally released) | Bad (blocks paw extension) | Excellent (released) |
| Neck preservation | bad (risk of trauma) | Excellent (neck released) | Excellent (neck released) |
| recommended use | Educated dog, walk with no tension. | Short journeys, need a grab handle. | Ideal for everyday, long walks, pulling dogs. |
How to choose and adjust the perfect harness?
In order for the harness to fulfill its protective role, Losteopath advises to check three points during dessayage:
- Elbow clearance: The ventral strap that goes around the chest should not be stuck behind the dog’s armpits. There should be 2 to 3 finger space to avoid irritating friction when walking.
- Neck clearance: The neckline of the harness should rest on the bones of the base of the neck (the shoulders), and not go up the throat. The trachea must remain perfectly free.
- The symmetrical setting: An ill-fitting harness that turns or glides to one side will change the dog’s center of gravity and create asymmetrical tensions on its spine.
FAQ: Your Frequently Asked Questions
Doesn’t the harness Nincite the dog to pull even more?
This is a tenacious received idea linked to the image of sled dogs. The harness offers better comfort to the dog, so if he is used to shooting, he will do it more comfortably. However, the collar “brakes” the dog only by the pain or discomfort it generates in the throat. Learning to walk on a leash is a question of positive education, not an accessory. For dogs that pull hard, there are Y-harnesses with a Anti-traction clip on the chest (front loop) who redirects the dog to his master as soon as he pulls, without blocking his joints.
My dog has cervical osteoarthritis, which equipment to choose?
The harness in it is here a therapeutic obligation. Any tension on the neck of a dog with cervical osteoarthritis will trigger painful inflammatory attacks. The harness will completely dissociate the walk from the painful area.
From what age can you put on a Y-harness?
As soon as the puppy arrives at home. The puppy’s skeleton is growing and its cartilages are very soft. Shock or violent traction on a collar can cause irreversible damage to its developing cervical. A well-adjusted and evolving Y-harness will accompany its growth in complete safety.
