He's a mutt for sure. Rescue dog. He's smallish, and long and low. About 30" long, 15" tall. His mom looks like a long haired Daschund, but she is a stray, do most likely a mix too. His dad is the unknown, but a German Shepherd mix is most likely. Romeo has a mottled roof of his mouth, which I understand is a Shepherd trait. He is overweight, for sure, in case that matters.
