Why don't you use your google fu and look up long haired red lab!
I know all 3 of the Cocker/Springer breeders/trainiers from Bismarck that I referenced earlier in this thread. Between the 3 of them occasionally there's an "Oops" breeding of a springer with a cocker. Happens when somebody doesn't catch a female in heat quickly enough. They've nicknamed the combo a "Sprocker". Before I owned him, my 1st male cocker sired such a litter in fact.
My dog and the mother springer were both very well pedigreed. That didn't make their mutt pups AKC anything other than mutts. They made great pets and hunting dogs, a friend got one of the females from the Oops litter.
There's no "Long Haired Red Lab" that's all Labrador Retriever. In fact, given your "Red Lab's" narrow head, a bit of Irish Setter isn't out of the realm of possibility either.
