Collies are one of our favorite breeds and for good reason. The Collie is not only an extremely beautiful dog with a lush coat, it is also one of the most intelligent of all dogs. Collies can be trained to perform all kinds of important tasks for their owners including herding sheep and working with children. Collies can respond easily to very subtle signals from humans, allowing them to learn complicated tasks that may be beyond the capacities of other dog breeds.
