All of our Berners are also happy retrievers. Haley, at 11 1/2 will still retrieve enthusiastically. In her puppy temperament test, she retrieved the thrown object 5 times, and the evaluator stopped at that point. (Always bringing it back happily, not just investigating).
Cassie, our 4 year old will play fetch with a tennis ball for as long as we allow. She has never willingly quit, and usually outlasts our Border Collie! It isn't a breed specific game! Some of ours has been cultivated, but Haley's was totally natural, and Cassie's retrieve drive is far beyond what has ever been taught.
