It's been almost 20 years since our dog Vince showed me how much I didn't understand about dogs.  Oh, I THOUGHT I knew all I needed to know.  But Vince's low growl and bared teeth said otherwise.  That began a marvelous journey of learning that has made life so much better for my family and my dogs.  Science has helped me understand both my dogs and myself better.  And that has made all the difference.
