Bernese Mountain Dog Harness Size
Most adult Bernese Mountain Dogs have a chest girth of about 31–41 inches, so size XL in our harness fits most of them. Always measure your own dog first.
Typical Bernese Mountain Dog chest size
| Dog | Typical chest | Our usual size |
|---|---|---|
| Male | 33–41 in | XL |
| Female | 31–39 in | XL |
These are typical adult ranges from a published dog chest size guide, and your dog may differ. The biggest dogs of this breed can go past our XL, which stops at 39.8 in.
A note for Bernese Mountain Dog owners
A thick double coat can add inches, so press the tape down to the body when you measure.
Check your exact size
Use the dog harness size calculator with your dog’s real chest and neck. Puppies need a new measurement as they grow.
Common questions
What size harness does a Bernese Mountain Dog need?
Most adult Bernese Mountain Dogs fit size XL in our harness, based on a typical chest of 31–41 inches. Other brands size differently.
How do I measure a Bernese Mountain Dog for a harness?
Wrap a soft tape around the widest part of the ribcage, just behind the front legs, then measure the neck where a collar sits.
Should I size up or down?
Choose the size where your dog’s chest sits closest to the middle of the range, so you can adjust both ways.
