Ask the breeder how big the sire and dam are. That's a good idea. My first basenji, who was a champion, weighed nearly 26 pounds when she matured. My 2nd one would have been about that, but thanks to steroids, we did good to keep her at 30. My current rescue is a giant. We won't go there. I first dreamed of a SMALL dog, maybe 15 pounds tops after years of being a BIG DOG person (rottweilers and chows). I don't see that ever happening.
