Australian Cattle Dog

Speaking of shepherds, not a lot of people have heard about the Australian cattle dog, and this is a true shame as they are adorable. You may have heard about them in passing as the Blue Heeler, and they are also known for their longevity, as they live up to 16 years!

This breed of dog is also known to not have a lot of health issues while also being one of the most intelligent ones you can find. Their high IQ is also paired with their extreme loyalty, and, much like a lot of the breeds on this list, they love long walks and need to have an active routine.

They are prone to boredom if not stimulated enough, and due to their high IQ, they are known to routinely outsmart their owners. If you are looking into getting a Blue Heeler, make sure you have the time to invest in them, or you may have your hands full of a little troublemaker!
