I figured I'd get more hits before you responded.Do you breed dogs? If its 100% genectics then why would you breed an undesirable trait in a RETRIEVER (you know -- outside the breed standard),is that not an ethics issuse in itself . A lot of breeders will cheat on paperwork to increase their sales and sell about anything--andlabs are smart enough--smart enough to not let blind people get hit by cars.(By the way alot of seeing eye dogs are golden--lab crosses)All dogs came from cross-breeding until a certain genectic type comes into being--what makes you think people have stopped(they aren't going to tell you when they trying to sell you a certain trait that your looking for) Pointers and Retrievers are two of the simpliest two to figure out what they are supposed to be doing--its in their name.Is that better on the caps lock?
