My "girl" is lab/springer mix. She's mostly black with the white springer markings on the face and chest. She's smaller than a regular lab, and can she jump. She also has the softest fur I've ever encountered on a dog.
What is it with the soft fur on these lab mixes? Every person that encounters my boy, the first thing they say is ,Gosh his hair is so soft.
Your girl sounds like a border collie.
