Mischief was the first female collie that we owned. She has been the best one so far too. She has guarded the cows, sheep, and goats from wild animals from the sky as well as on the ground. She loves people, but holds strangers at bay until they have been introduced to her. Barlina is one of her puppies. Mischief has passed away. And we will miss our best dog.
