I have a Chocolate/black lab,she is a year old and she has a determind personality to impress us while hunting. She sits, and lays down by voice camand, and retrieves by hand signals as well as we reliese her on her name, I've been the only one training her so she only usually listens to me, but I was wondering if we could et her to listen to everyone in he family, as well as on whistle command, would it be to hard to transfer her from hand/voice commands to whistle commands?

I don't have any hunting experience and see few post from those that do on the net. Likely the nets loss. I would think a well trained dog would respond to anybody showing leadership and giving the correct commands or using the whistle. The rest of the family may need to learn a little about leadership. One good web page is Establishing and Keeping Alpha Position, Letting your dog know you are the boss (http://www.dogbreedinfo.com./topdogrules.htm)

Some of the books in the sticky at https://www.askmehelpdesk.com/dogs/information-articles-our-dogs-expert-labman-53153.html#post251804 would be good too.
