It's impossible not to make comparisons. Boz was an angel, easy to live with from the start. Wilma has required training, consistency and love to learn to walk peaceably on the leash and to not freak out when she sees other dogs. There have been frustrations, family discussions and time-outs for each of us. But with every step backward there's a forward leap. Wilma wants to be part of the family and she demonstrates it at every opportunity, unless she forgets. In other words, she's a normal dog.
And she has a tail. Boz's was removed by someone before us who might have been loving but certainly was ignorant. Wilma's tail is a fascination. Sometimes she wags it so hard it has a circular motion. Among her many nick-names: Propeller butt. (Who needs cable?) She's incredibly and immediately expressive at both ends, though sometimes she uses her outside voice indoors. That's ok. It would never occur to a dog to hide her feelings. Even Boz used to wag his little stump like crazy, though he almost never barked.
Because Boz's tail couldn't be heard from a distance and because he'd lost his bark, he was forced to communicate in other ways, like a look, a movement or even a breath. He taught us Doglish slowly, over time. With Wilma we're all speaking it now.
Another difference between Wilma and Boz: Boz sat symmetrically. Wilma sits like this.
A similarity: both sun bunnies.
