The only down side to earthwork....bit risky..never the less still worth it, my first dig was about 4 months ago it wasn't my dog(if that still counts) but anyway it was on the slip, an old landslide on the mountain, we put the collar on and netted the holes up then put the terrier in (from ken gould lines i think) minutes later he started baying for about half hour, it turned out that a vixen had bolted but got stuck and the terrier killed one in the hole he dragged a dog fox out turns out he had bit the nose clean off and eat it
terrier had a few scratches nothing bad.
