About 85% of all the work my terriers do is earthwork. The other 15% percent is quarry they find in brushpiles, rubbish piles, etc. I try to work them to earth if at all possible. I also own a female cousin to the pup that is mature and a firecracker finder/stayer. She is more of the smart mixer type and doesnt kill every piece of quarry she works but she is HONEST, a great finder, and has shown she is there till dug to, and that's all I ask of her. I can spade quarry with ease. atb
