Dean Anderson, a.k.a. the "Cow Whisperer," has a cooperative agreement with Future Segue of Las Cruces, N.M., to develop his patented cow "roundup" collar for commercial use as a virtual fence.

It locates cows with a Global Positioning System receiver tuned to satellite signals. The collar is similar to those used to train dogs
