Spot on FM. It's the stigma that comes with a dog getting stuck in. That all these dogs are laid up for weeks on end ok some circumstances are unavoidable and I have seen stupid fool hardy dogs career last not long at al, but I know plenty digging men who hold dogs that are stuck in so to speak and nothing else will keep it's quarry pinned, definitely yapping won't. These dogs can be brought on for another dig that day or tomorrow or the weekend after. So the arguement a yapper is more use as it can be dug more often is dead in the water in our parts as they would be the ruination on good earth's.
