Chumlee was born to friends of ours who own two adult min-pins. Chumlee's mom is part Chihuahua. We have had him 15 days and he's a tiny little ball of energetic fun. He's a bullet when we let him run and he is already able to outrun me when it's time to finally come inside--trouble! Another special part of Chumlee is that he slept through the night from the beginning without using his crate as a bathroom!
