These dogs are loyal, willing and loves to please. They are excellent with children. This dog needs to be a part of the family and prefers to be with its people all the time.
Generally they can get along well with other pets and are not aggressive. They should be introduced to newcomers, since they are territorial, but will quickly warm up to those the family accepts. Great Swiss Mountain Dog is an excellent, courageous, alert watchdog who will bark at strange noises and intruders. They will do okay in an apartment if sufficiently exercised. They prefer cool climates. A small yard is sufficient.
The GSMD is perfect for you if you have children and are looking for a great family dog, who will please and protect the whole family.
