Only thing I would suggest having with ur tight bred dogs is to get another tightly bred dog that comes from producers that is unrelated. Then take those oils back to ur tight bred inbred dogs. That way u always have a touch of hybrid vigor. That unrelatd dog is what people forget the most. Those hybrid dogs will ALWAYS pop and be grat products for u
That's funny you mention that Josh. I just happened to pick up a pup last weekend that fits your description. Just not sure when that cross would need to be bred in?
