You can see some of the dogs that do this at my website http://duffyscavern.org/dogges_of_the_earthe.htm
I just returned from working one this weekend and will be back in for three more in the next 5 weeks. It is a good time of the year to for my dogs.
Sometimes I supply the rats I get from a local snake store. One day I was sneaking them back to the laundry room when the bottom of the cage fell out. The rats fell out, the dogs heard the racket. I got three and they got three after eating a hole in the dry wall trying to get one of them.

No complaints from me, that is their job.
Clubs that do this are always looking for practice sites. Maybe you can offer your place.
