My neighbors have a dog that looks like that. Lighter colored coat, but she looks just like a shepard with really short hair. I have wondered what she is. I will ask them again. I know they told me once but I don't remember what they said.
I believe what we call that is a "dog". It is also referred to as a "canine" "get off that" "SIT" and "SHUT THAT THING UP!!!". Researchers find that this "dog" is good for blood pressure and stress in "humans".
