A relatively young Schnauzer breed dog, semi-drooping ears that is holding some apartment keys in its snout and around it there are 2 other schnauzer dogs that are taller, and one of them has his ears standing up and the other has his ears half down with his face a little whiter than the other two, It must be a very tender and advertising image for a real estate rental business.
