For a small, delicate breed like the Havanese, a well-fitted harness is generally preferred over a collar for daily walks. The Havanese's trachea is relatively fragile, and traditional collars that apply pressure to the throat during pulling can contribute to tracheal collapse — a condition that small breeds are already predisposed to. A step-in or over-the-head harness that distributes force across the chest and shoulders provides much safer control without putting any strain on the neck or airway.
When selecting a harness, look for adjustable designs with at least two points of adjustment — at the chest and around the girth — to achieve a snug but comfortable fit. The harness should sit flat against the body without rubbing under the armpits or shifting during movement. Padded straps help prevent chafing against the Havanese's skin, which can be particularly sensitive beneath their long coat. Mesh-backed designs offer better ventilation during warm weather walks.
A flat collar is still useful for holding identification tags and registration information, even if you use a harness as the primary walking attachment. Choose a lightweight collar in the extra-small to small size range, typically fitting neck circumferences between 8 and 12 inches. Breakaway collars that release under pressure are a smart safety feature for dogs that spend time in yards or around furniture where a standard collar could catch and cause strangulation.
Leash choice should complement the harness or collar setup. A standard four-to-six-foot leash made from nylon or lightweight leather gives you adequate control without dragging on a small dog. Retractable leashes are popular but carry real risks — the thin cord can cause friction burns on skin and the locking mechanism can fail, giving your Havanese unexpected freedom near traffic or other hazards. If you prefer the variable-length concept, consider a long training lead that you can manually gather and release as conditions require.
