Thanks for reccomending Glen Johnsons Tracking Dog. The nice people on the web dispatched it really fast and Ive been poring over it ever since. Love the photos of 10 year old half blind toy poodle on his tracking line with his glam owner and her blonde beehive, and the tiny little Maltese terrier. :D Sections on non natural retrievers is very helpful too. Should make our walks more interesting and give Morse a 12 step programme for his rabbit addiction once I get the hang of track laying.
