Linda Virginia Beach, Virginia 10/1/2012 1:14:02 PM I am working with a 3 year old (VERY food motivated) Pomeranian on casual agility. "Casual" meaning I have no intention of his competing as I currently work with him from a wheelchair. Even so I want to train him as correctly as possible within the framework of my disability and homemade agility equipment. I found the article to be very informative in its explanation of the importance of keeping up a dog's interest and enthusiasm. Good job.
