I grew up with a 'mutt' that was 1/2 rat terrier and 1/2 Basenji. Smartest and most 'polite' dog ever. She hardly ever barked, like her Basenji half. She had an astute instinct for where she was 'allowed' and where she wasn't. When my sister was a baby, Tipper would lay right next to the blanket but never touch it. And she knew the difference between her toys and the baby's toys, and never touched the baby's toys. She was just amazing.
