A friend of mine had an unplanned litter of Lab (sire) cross Cocker (bitch) pups. He has 2 dog pups, 14 weeks old left. They are solid black and other than their ears looking very slightly bigger, for all the world look like lab pups. The mother is actually off superb working lines.
That's what happens when you leave the kids to walk the dogs when on a fishing trip.
If interested pm me and I will pass you his details.
I have some photo's now I can email you if interested.
