I have two miniature schnauzers, Vanilla & Spice, who are now 9 & 8. Vanilla is a white male(he picked his own name ,incidentally)& Spice is a black female. They are mates, puppy-free!(Both fixed as puppies-even though they are purebreds)Spice especially likes to play quality-control whenever I start laying blocks out. I love my four-legged babies!
