Of course in Permiculture we try to stack as many functions as possible into everything we do.
Here are some of the possible stacked functions I could see from this dog we just got the kids for Christmas.
Hunting, Alarm, protection, guide dog, live stock protection(not likely easy), small cart pulling, and... well... Labradoodles don't shed their fur and are hypoallergenic. They just grow A LOT of hair that is curly and long kind of like a sheep. So... um.... who needs sheep for wool if you have a Labradoodle or two! lol
Our puppy is now 9 or 10 weeks old and we had her trained to sit, lay down, touch(my hand with her nose), acklowledging her name, and ringing the bell on the door to go outside all in the first week(after getting her @ 8 weeks) without even really trying. Just playing around. She is highly intelligent and getting sneaky already with grabbing things she is not supposed to have and hiding with them to give them a chew. However, I think she is going to be possibly the smartest dog I have ever had.

I keep seeing the bird dog side come out in her. She loves to stalk her toys much like a cat does. Doing the low crawl towards it and then pouncing on it. Followed up by a good chomp on the head/neck and shake of the head. I have even seen her stop and kind of do the perfect "pointer" stance a few times when she spots a rabbit in the yard too.
Just putting my thoughts out there.
