Puppy?
Size for the adult and use a divider. A crate bought to fit a puppy is outgrown in weeks, and a crate with a spare end stops working as a den. Buy the adult size and move the divider back as the dog grows. A harness or collar is the opposite: buy for the dog you have now, because adult-sized straps slip on a puppy.
Is your dog a mix?
Mixes vary a lot. Measure your dog. A breed figure describes a published standard, and a mix is not held to one. Two dogs from the same litter can land two sizes apart on the same chart.
Measure your Bernese Mountain Dog
The tables above start from a published breed range. This starts from your dog. Crates need a body length and a standing height, plus 4 in of room.
Size your Bernese Mountain Dog
Enter what you have measured. Every answer below is the maker’s own published range against your number — a starting point, not a fitting.
Published range for the Bernese Mountain Dog: 32 to 40 in chest, 20 to 26 in neck (Hund & Shore, "Dog Collar & Harness Size Chart by Breed").
Measure your dog and enter it. A published range is a range: the boxes below stay empty because the middle of a range is a number nobody published. Full Bernese Mountain Dog size chart

Common questions
- What size harness for a Bernese Mountain Dog?
- On the charts published by their makers, a Bernese Mountain Dog comes out at Julius-K9 IDC Powerharness 1 to 4 (4 sizes), Ruffwear Front Range Harness M or L/XL, Ruffwear Flagline Harness M or L/XL (by published chest girth), with 16 of 19 charts giving a size. Size labels are not comparable between brands, so read the range rather than the letter. Measure your dog's chest girth at the widest part of the rib cage and check it against the maker's own chart before you buy.
- What size crate for a Bernese Mountain Dog?
- By the makers' own weight guidance, a Bernese Mountain Dog comes out at MidWest Homes for Pets iCrate Single Door Folding Dog Crate 42-inch or 48-inch, MidWest Homes for Pets LifeStages Single Door Dog Crate 42-inch or 48-inch, Petmate Sky Kennel 40" or 48". Weight is the rougher route: a crate is sized on the body. Measure your dog from the nose to the base of the tail and from the floor to the top of the head while standing, add 4 inches to each, and compare that with the crate's interior, not its outside.
- How big does a Bernese Mountain Dog get?
- An adult Bernese Mountain Dog is 25–27.5 in tall at the shoulder for males and 23–26 in for females, 80–115 lb for males and 70–95 lb for females. Published sizing charts give a chest girth of 32–40 in and a neck of 20–26 in. These are breed-standard ranges, not your dog: individual dogs sit outside them. Measure your dog.
