What some commenters seem to have taken Iteeres Rottweiler Tattoos I love mom shirt issue with is your mention of the need to “be aggressive”. I think that this is simply a misunderstanding. Any dog that has to protect its owner from an attack will almost certainly have to behave aggressively to some degree. However, that fact should not be confused with having to have a dog with an aggressive character, in order to have one that can protect you when necessary. I have trained many police dogs. Those dogs are trained to attack on command and make their target stop. As long as that target stops, the dog will let go of the target and sit or stand by until its handler arrives to take over.
The dog will only persist in attack or attack again Iteeres Rottweiler Tattoos I love mom shirt if the target resists or makes another attempt to getaway. The handlers of these dogs can also have them break off their attack before they strike if the target stops and surrenders. Although those police dogs are well capable of bringing down a large and fit man, they are also extremely stable and can be walked through crowds of people and petted by children and adults without any problem. There are many breeds that could fit this bill but, of the ones that you mention, in my opinion, the German Shepherd stands head and shoulders above the others.
