Using data from a University of British Columbia professor, PetBreeds has compiled a ranking of the least-intelligent dog breeds. These particular groups take awhile to understand new commands, and have trouble following a command when it's initially given.
This dog should always receive constant socialization in order to avoid nipping. Bloodhound. The Bloodhound is an incredibly talented scent hound which is why they are most often used by search and rescue teams or professional trackers. Unfortunately for this hard working breed, bloodhounds are not considered the smartest of dogs.
The borzoi, also called the Russian wolfhound, is a breed of domestic dogs (Canis lupus familiaris). It is descended from dogs brought to Russia from central Asian countries. It is similar in shape to a greyhound, and is also a member of the sighthound family.
I DO NOT agree with the Afghan Hound being the least intelligent dog! Absolutely ridiculous…I have grown up with different breeds of dogs since I was born, my Afghan Hound Fallon is by far the smartest and most “human like” dog I have ever had!!!! These Dogs are not your typical sit, stay, fetch kind of canine.
