I was very impressed with a site I recently came across that supplies guard dogs trained to different levels according to different requirements. The different levels are related to the attack, aggression and guard skills that the dogs have.
Level I
Level I dogs are classified as companion dogs and are trained to show aggression as well as stop at any time, simply from a command given by the dog’s handler.
Level II
Level II animals are classified as protection dogs and they have all the attributes of the level I dogs however they are additionally trained to attack on command
Level III
If you need a more advanced attacking dog, then you may want to consider the level III animals, they are trained to specifically attack the weapon hand of the attacker, this means they can quickly disarm an intruder or aggressor.
Level IV
Top of the range executive protection dogs do all of the previous as well they can be trained in specific languages and also they can execute an extended down-stay.
The great things about dogs is that not only can they be trained to protect, they are also faithful companions and very good with children. These dog’s will give their lives to protect you.
