I haven't researched this, but is there any evidence of tool use in dogs? If not, could Black Jack be the first? I think I may have a genius on my hands. There is only one hole in her bed that she herself made (okay, accidentally). She now uses that hole consistently to help her manage long bully sticks. I tell you, a genius, no less. Okay, perhaps a bit of a stretch:) But, even border collie lovers might agree she's pretty cute. Yes?
