Mack,
In the USA, Service Dog means a dog trained to assist the disabled. These dogs are selected from non aggressive pups and then trained to be "people friendly". They have to be, they go everywhere with their human partners.The disabled are the group most victimized by crime.
Boxers, the first breed ever to be used as Service Dogs (1910), today partner people who are blind, deaf, lame, in wheelchairs etc.I have records of over 700 disabled Americans who are today, fortunate enough to be teamed with a Service Dog Boxer.
Not one of them has ever been successfully mugged. Not one of them has had their home successfully broken into when their Boxer Service Dog has been present.
Boxers are not, nor were they ever meant to be, "attack dogs". They are by their very nature, guard dogs. When I read of all the flashy, dramatic training some people put their Boxers through, when I read of how some people think that modern Boxers are not capable of protecting people, I have to laugh. I think of the statistics I just cited above, look at the aging, 70 pound partner at my side and ask myself if those doubters, those "protection" fanatics, have ever lived with a Boxer.
You are safe (twice over) my friend.
