Here is our Border Collie mix, Molly. We believe the mix is husky, though her coloration definitely says Border Collie. Border Collies are usually 35 - 40 pounds. Molly is every bit of 70 and all muscle. I believe that is the Husky coming out in her. She is the sweetest dog though days at the dog run are often interesting as, true to her roots, she tries to herd the other dogs. Something that is often met with growls and showing of teeth!
This is our female Manx (really a bobtail, her tail is about 2" long) when she was about 12 weeks. She is full grown now.
