5. Doberman
Dobermans are great guard dogs. Their mental abilities are so high that they are extremely easily to train. Unfortunately, many people think that dobermans are agressive because movies show these dogs as the most evil species. Allright, we can not say that dobermans are not agressive at all. But they are very attached to children in the family and will never offend them. Even more, these dogs are loyal friends and reliable guards.
