that calculator says Malu will be about 29lbs, which is still pretty big. I was hoping he would be a little larger anyway, most of my friends have larger dogs, labs mixes and hound mixes. So he should have no problem "hanging with the big dogs".
I was browsing through that book a little more. It actually has some pretty interesting data on different experiments they did with the 5 different breeds. Its kind of neat to see how the Basenji's compared to some of the other breeds.
