As we all know, dogs are not only for keeping as pets, but also good tools for supervising the house. When choosing a dog suitable for guarding the house, we usually consider the dog's alertness, loyalty and courage. Here are some suggested breeds, all of which are good house-keepers.

2. Rottweiler
