whats the point? you can get working dogs docked legitimately and that is not likely to change
Where is the bobtail gene from? - the only breeding I saw that replicated this involved corgi x's? It certainly isnt from springer or lab so there is something you are not telling us.
Waste of time, stop breeding these dogs, they are not adding anything to whats already out there, it isnt fair on the dogs, they will probably end up in pet homes, if they are lucky, cos they dont offer much to anyone wanting to work them - there are too many mongrels and puebreds ending up in the pounds as it i
