Do Saint Bernards make good watch dogs or guard dogs?
The size of most Saint Bernards combined with the tone and volume of its bark will be enough to discourage most intruders. If an intruder gets by the size and bark, your may find that the Saint Bernard has decided to lead the intruder straight to the family treasure, since he would much rather make a new friend than protect your valuables. The one exception to this is when a member of the family is being threatened. Occasionally, when found in this situation the Saint Bernards instinct to protect those he loves becomes very apparent. This is dependent upon blood lines; ask your breeder how his or her Saint Bernards typically react in situations such as these. Your Saint Bernard will learn quickly to recognize your family and friends and seek to become their friends.
