What Breed is My Dog?
The broad chest and legs are definite signs that it is an American Bull Dog. It is not a boxer (people often confuse the two)
What Breed is My Puppy?
My dog looked similar to yours when he was a puppy. The shape of the face makes me think he has a little (very little) boxer. Also, his colorings and fur make me think he is also mix with both German Shepherd and Chow.
