my opinion on a dog getting dug to over the 30 mark each year is that it will obvisouly not be hard dog, that goes to ground trying to eat its quarry, but a dog that worrys the arse of the quarry, baying like mad, mixing it a little bit if need be, but being sensible about it. a dog that uses its voice freely more than its bite can be dug to 3/4 times a day. i prefer a bayer. saves time and money.
