St. Bernard (dog) an amiable yet hard worker. St.Bernards have retained their natural ability for scent work and depending on the skill of the trainer and the talents of the dog, St. Bernards can participate in tracking events or even become involved in search and rescue work.

Plinlimmon, a famous St. Bernard of the time, was measured at 95 kg (210 lbs) and 87.5 cm (34ins), and was sold to an American for $7000. Commercial pressure encouraged breeding ever larger dogs
