#20 – Collie
If you’re not going to be annoyed by your Collie being called “Lassie”, because of the popular movie of the same name, then you’re all set to own this awesome dog breed.
This breed of dog is smart, and loyal to its owner, and its behavior is predictable. Interestingly, Collies do not only love their owner, but they also love to socialize with other people as well. The best characteristic about this dog breed is that they aren’t aggressive and that they will only bark if they sense danger, and, of course, will protect you when it is needed. They make a terrific watchdog and are easy to train. The average life span of a Collie is 14-16 years.
