On many two lane roads, in no-passing zones, there are signs that tell you when a passing zone is coming up: "Patience Pays; Passing Zone in 3 Minutes." No matter how annoying that slow-poke is in front of you, you know that pretty soon you'll be able to get by him. So, you possess your soul in patience and look for a better radio station. And soon enough you're in front of him and singing along with your favorite song.
So it is with dog training. You see a problem, work at it, and little by little, you've put that problem behind you. Tango has had issues with other people and dogs. A few months ago we couldn't walk into our Agility class building without him firing up at whoever (or whatever) was walking around. But last night we not only walked into the building with confidence, but he was able to stay at the start line of our sequences, leash off!, with a big dog not 2 feet away from him, and pay attention to me. He started when I told him to, and he stayed with me. What a good boy!!!
Of course, that's not to say that our work is done. It never will be. I'll remain vigilant of the people and dogs around us. We'll keep training our start-line stays. But patience really does pay!
