They become very affectionate to anyone they meet, and are great with children and other animals and this fondness with children really is very much a characteristic of the breed. The first sight of a St. Bernard creates an uncontrollable feeling to stroke it, because of this affection it will show you and also because of its lovable gentleness (as well as that fantastic fluffy coat). Their size means often they can bump into things (chairs, flower pots, unsuspecting five year olds), and this is not meant maliciously; but do remember this when letting really little children play with them; or if they are going to be around frail people. Because of this size and weight as well, though, they’re not the easiest dogs to get around long distance; and they’re is a high chance that they will not fit comfortably in your car (on a side note, even on a cool day, a St Bernard will get very hot in a parked car because of its thick coat. It’s their version of a woollen jacket, but remember they can’t take it off.) St Bernard’s rarely wish to bark, and seldom pose any threat to wildlife (perfect if you live near livestock); but because of their loyalty they will look defend you or your possessions.
