I agree that instincts will take over as far as the hunting aspect goes BUT having said that I have owned one truely intelligent dog in my life, she was my best bud for a long time. Daisy picked up on any and everything I showed her. NO BS, in 2009 I went to the beach with some of my buddies and I swear on my life that I taught her how to get a beer out of a cooler in less than 30 minutes......the very same day we were walking down the crowded beach and I started telling her to go get me a beer, she would run up to the first cooler she saw in a crowd of people grab a beer and bring it back to me..........needless to say she was a BIG hit lol, we must have got her to grab us 20+ out of different coolers and the response from the people was always the same, they thought it was the funniest thing ever, met a buncha pretty ladies using that tactic over the course of the week

anyway, that dog was a once in a lifetime type dog, I have owned labs since she passed but I always end up buying them and giving em away a few months later because they don't compare...........I did have 1 that I thought was gonna do pretty good but she ended up disappearing never to be seen again.
