For Lhasa Apsos, a harness is generally preferable to a collar for leash walking. The breed's compact build and relatively delicate trachea make them susceptible to injury from collar pressure, especially if they pull or lunge during walks. A well-fitted harness distributes force across the chest and shoulders, eliminating strain on the neck. Step-in harnesses are often the easiest to use with a Lhasa Apso's long coat, as overhead styles can tangle or mat the fur during application.
When sizing a harness, measure the dog's chest at its widest point and refer to the manufacturer's specific sizing chart rather than relying on generic small-breed sizing. A harness that is too loose can allow the dog to back out and escape, while one that is too tight can restrict breathing or cause chafing beneath the coat. Adjustable straps at both the chest and girth points provide the most customizable fit and accommodate seasonal coat changes or weight fluctuations.
A flat collar should still be worn for identification purposes, even if the harness is the primary walking attachment. Choose a lightweight collar that sits comfortably beneath the coat without creating mats or pressure points. Rolled leather or rounded nylon collars tend to cause less coat damage than wide, flat styles. The collar should be snug enough that two fingers can slide beneath it but not so loose that the dog can slip free.
Leash selection for this breed favors lightweight materials and a length of four to six feet. Heavy chain leashes or thick leather leads are unnecessary and can feel cumbersome attached to a small dog. A thin nylon or biothane leash provides durability without excess weight. Retractable leashes are generally not recommended, as they offer less control and can create dangerous situations if the dog darts into traffic or toward a larger dog before the lock engages.
