One thing clicker training gives us is a new level of trust and communication. You may have noticed this with your pets. It's particularly startling and, to me, touching, with captive animals that could never be pets; it makes their entire care much more humane.
Writing a book is like having a baby. There is never a convenient time to do it. It's much more work than you remember from last time. And it usually takes longer than you thought it would.
For six years I have been writing a monthly letter to you. In the beginning, back in 2002, "Karen's Letter" was usually about new products and events, but gradually I began using the letter to talk about the science of training, and about the impact of the new technology we are developing from that science.
