Dogs intelligence

Irondog, really it was easy BUT she was already a rock solid retriever, she knew all her commands and listened everytime. I didnt back when i sent her, id say git me a beer everytime....(it woulda been pretty embarrasing comin openin day of dove season in a field with 10+ hunters who all have coolers lol)....anyway She would retrieve anything i threw so that day i grabbed a beer and started playin fetch with her, after maybe a dozen reps i started throwing the can into an empty cooler....she acted like the cooler wasnt there.....next step i added a dozen full cans of beer and then tossed the empty in again, told her to get it, she did and as soon as she got back i sat her back at my side and sent her again.......at first the cold can threw her off but it didnt take her long......next thing u know we are sittin on the porch and she is making constant trips to the cooler......that dog flatout lived to retrieve, it was her life i have never seen another the enjoyed it as much as she did.....i couldnt probly write a book about that dog....she truely was my once in a lifetime dog.
