The only caution I will give with the retrievers (I have a black lab) is that they are hard wired to "retrieve". My gentle giant goes nuts in bark mode whenever my grey flaps furiously. (He does that when he wants me, or food, or whatever.) I'm trying to retrain the lab but it's tough to knock out an inbread instinct. Interestingly, my grey will fly away if I bring him out when my 2 year old and 8 month old granddaughters are in the room and fly back to the room where the dogs are. He doesn't seem to see the dogs as a danger but these two little girls are a threat. Go figure.
