30. Yorkshire Terrier
Despite its very small stature, the Yorkshire Terrier breed should not be underestimated! These are very smart and energetic dogs that learn very quickly (they can be house trained in just a few weeks!) and retain knowledge gained for their entire lives. Additionally, their emotional intelligence is very high and they bond with their humans very quickly.
29. Puli
Puli dogs are absolutely known for their look, which is undisputedly unique. While some people describe them as looking like a mop, their signature look most definitely set them apart. Say what you want about their look, these dogs are very intelligent. Mark Zuckerberg and Priscilla Chan owns a Puli dog, so you know they must be smart!
