Maggie, our four month old Sheltie, has become a great friend with Dougie, our two year old tri-color Collie. When we all rise in the morning, just about the first things the puppy does is run up to Dougie and start playing with him.

I gotta admit, it's kinda difficult to catch these two "opponents" engaged in head-to-head combat, so please forgive the cropping that cuts off parts of their bodies!
