Leonberger profileThe Leonberger is a medium-sized Working dog originally from Germany, typically weighing 41–77 kg with a double-coated coat. Being a moderately active dog, a Leonberger needs a harness matched to its actual build and coat — not a one-size-fits-all pick. This guide covers what to look for in a harness for a Leonberger, then links filtered picks that match the breed's frame.
If you've tried collars on your Leonberger, you already know why most owners switch. Collars put pressure on the neck and trachea — and on a strong, energetic dog they don't actually stop pulling. A well-fitted harness redirects pull force to the chest and shoulders, where it's safe.
What to look for in a harness for a Leonberger
- Right size band: based on the Leonberger typical weight (41–77 kg), look for harnesses sized for that range. Always measure your dog's chest girth at the deepest point — sizing varies by brand.
- Reflective stitching — Irish winters mean dark walks. A 5p add-on if it's stitched in.
- Easy on/off — overhead designs are a no-go for most dogs. Step-in or buckle-side designs save fights every walk.

Common mistakes
- Buying by weight alone. Two dogs at 25 kg can have very different chest girths. Always measure.
- Over-tightening. Two fingers should fit between harness and dog at the shoulders.
- Picking a harness that lifts off the back. The Leonberger's joint risks mean handles directly over the spine should never be load-bearing.
Harness for a Leonberger: common questions
What size harness does a Leonberger need?
Leonbergers typically weigh 41–77 kg, which puts them in the medium-sized range, so start with a harness sized for that band. Sizing varies between brands and individual Leonbergers differ, so measure your own dog and check the maker's size chart before buying.
What should I look for in a harness for a Leonberger?
The Leonberger has moderate energy, so aim for a harness that balances comfort and durability. Above all, match the harness to this breed's actual build rather than buying generic.
Does the Leonberger's joint risk change which harness to buy?
It can. Leonbergers are prone to hip or elbow problems, so favour a harness that supports rather than strains the joints and keeps daily movement easy as they age.
