They are two different Swiss mountain breeds. The Bernese Mountain Dog is tricolor — black, white and tan — and smaller: up to 70 cm (28 in) at the withers. The Saint Bernard is white and reddish and considerably bigger: up to 90 cm (35 in) according to the FCI standard. Both are calm family dogs, and neither does well in the hot lowlands.

## Which one should you choose?

- You want a large but manageable dog in a house with a patio: Bernese Mountain Dog
- You have a lot of space and want a giant dog: Saint Bernard
- Drooling bothers you: Bernese Mountain Dog
- You live in the cool highlands, from about 1,800 m (5,910 ft) upward: Either; the Bernese is the one we can help you choose

Neither is for you if you live in the hot lowlands, in a small apartment, or if you cannot take on what it costs to keep a dog of this size. In those cases the honest thing is to say no.

## Why do they get confused?

Because both come from Switzerland, both are large, hairy mountain dogs, and both have white on the chest and face. The quick way to tell them apart is the base color: the Bernese is black; the Saint Bernard, white and reddish. And size: next to an adult Saint Bernard, a Bernese looks medium-sized.

Another common confusion, in Spanish-language searches, is between “Bernés de la Montaña” and “Boyero de Berna”: those really are the same dog — the Bernese Mountain Dog — under two names.

## Which adapts better to Colombia?

Neither to the hot lowlands. Both are cool-climate dogs, and the bigger the dog, the worse it sheds heat. We recommend the Bernese from about 1,800 m (5,910 ft) upward — Bogotá and the Sabana, Boyacá, Pasto, Manizales, eastern Antioquia — and with reservations in the lower temperate zone.

We cannot give you a city-by-city recommendation for the Saint Bernard, because we do not raise it: what we say about it on this page comes from the FCI standard, not from our experience. If it is your breed, look for someone who raises it with health tests and ask them about climate.
