It’d be very difficult not to mention Lassie when talking about Collies, so there. Lassie.
Now that it’s out of the way, Collies are a very popular breed of large dog, not only for their obvious ties to classic literature and film, but for their sharp minds and friendliness. These loyal dogs rarely show signs of aggression unless their owners are in need of protection. Equally fearless and gentle, the Collie is good with kids and can be the ideal addition to a happy family.
