I was agreeing with their list until this one:
#2 Dumbest: The Basenji is considered the second least intelligent dog breed, but hey, it could be worse.
I owned a Basenji and was around another for years. I found them to be extremely intelligent.
The smartest and best dog I ever had was a bearded collie.
Best dog all around, just like an American, is a mongrel mutt!
As for beagles being dumb, I have a part beagle....stoopidist dog I ever owned.
That is why you should have another Basenji. Our little one tricks us all the time and has a vocabulary she recognizes words such as walk, food, bone, outside, off, shmackos, dog park and shower as well as her training which was very simple to do all you have to do is to be patient. We taught her sit, down, shake, talk, over (roll over), stay and leave it. They are a lot of work but are worth it as I am sure you know! :D
