Training the adult St. Bernard requires gentleness, although if the St. Bernard were to pull the leash, it could become a real struggle for the owner. Hair trimming is not a problem, as the dogs of this breed have hair of a short to moderate length. The St. Bernard’s coat color should be orange, dark red, red and brown with white markings, or white with markings of these colors all over the body. The St. Bernard has a kind and trustful nature, but if he lashes out at anyone, it can be a terrifying sight. When considering this breed as a pet (and indeed, the St. Bernard makes a wonderful friend), first consider if you are able to accommodate the difficulties that come with owning such a large dog.
