Don and Tango have their certification test on Saturday. For the last couple of weeks they have been out training 5-6 times a week to make sure they are ready. Last night they worked on searching alleys. It was a particularly tough test for Tango because there was virtually no air movement. Instead of smelling an article many feet away and zoning in on the scent, she had to be almost on top of it before she could smell it. She got a real surprise when she found a hidden hammer just as a dog on the other side of the fence starting barking and charging the fence. Even with all the challenges, she managed to find all of her articles.
