That dog knew he what he was doing. he found a spot to freeload and sponge off of you for the rest of his life!! 
And YOU are the lucky ones too, as he will be a great little dog, I am sure. And he is definately a cutie. Congratulation on the new friend.
Hard to tell age and size in photo, but I would say he may be part rat terrier, but not sure about the rest. Loooked a lot like our Manchester Terrier when she was a pup, but no brown
No matter, you guys did a good thing and he will be a joy to have. (Hide the shoes, he looks like a chewer!!!)
