For me I would pick a German Shepard because they are the second most dangerous dog in the world and I would like to have a guard dog.
German shepherd.
I think it would be a Saint Bernard or a German Shepard.
Now if a German Shepard and a boxer were fighting they would be equal but if you are talking about walking the dog than the German Shepard would be far stronger! i know this from experience because i have a purebreed boxer and purbred German Shepard and they are both male and the boxer is above average size for his breed and yet the German Shepard is far harder to walk! i hope this answers your question!
People call the Greyhound the "cheetah" of the dog world as it can run faster than any other canine breed. Bred for speed, they are built for it like no other dog. Long, lean, with tremendous lung space and a huge heart, the greyhound can reach incredible speeds up to 45mph.
