I have a new baby Basenji girl, Ruba, who is just about 9 weeks old. She's a real sweetheart, and overall not unlike other puppies I've been around. Occasionally she growls a bit when you try to pick her up. It's usually when she's really tired or engaged in doing something else. Also, the growling is by no means really nasty.
Is this common to the breed? What's the best remedy?
