Just to clarify, I do own a Guide Dog named Stafford. He's a fairly good-sized Labrador. The reason I was wondering if Kirk's dog got distracted was that I've had that problem with Stafford. He sees a cat and I know it immediately because he speeds up and his tail starts wagging. I think he actually likes cats! He also gets excited when he sees certain people. I usually have to make him stop and I have him sit and lay down a few times. This usually gets him back under control and he realizes who is in charge. Other than that, he is a very calm and layed-back dog. I know what you mean about not having much time to react when you walk fast, though. I usually go at a pretty good clip myself, and in fact, that is the reason I got the dog.
