I have a one year old, energetic lab that I've been working hard to get ready for the upcoming duck and upland season. He's working close enough in, with the need to occasionally bump him with the collar when he ranges to far out. My wife hikes up the mountain on which we live everyday and wants to bring the dog along. Up till now in have been demanding that she puts him on leash, although when I "demand" anything with my wife, I get THE look and I'm sure she doesn't always leash him. Is a dog able to differentiate between when he is hiking with my wife and hunting/training with me? I'm thinking no, but my last lab that just passed away was able to split up his time between us. Whatcha think?
