Please adopt one. There are many organizations that have them. Also, check the shelters. Not sure about your area, but I suspect you could get one that needs adopted. If you need help my wife can find one for you. Do you know how many dogs are put down a year? Please consider adopting.
You may want to call the Teresa Cline Gallery. Teresa is very active in the adoption community and has 4 labs herself. She has sponsored a bunch of labs for adoption. I am sure she can find you a great lab puppy or very young one that you can adopt that will already have shots, has been checked out medically, and temperament tested. http://teresaclinegallery.com/blog/info/contact-teresa-cline-gallery/
