A recent WuH (the German Shooting Times) 5 page magazine article discusses the best way to train a deerdog as opposed to a scenthound.
The article refers to not only the usual experts (Borngraeber & Muller) but also to a recently completed thesis on tracking by Donat.
The conclusions are interesting:
1 Using blood on trails is of more use for the handler than for the dog.
2 The dog tracks: A soil changes caused by the cloves B scent from broken plants C scent caused by the layer of the trail D Scent caused by the bacterial working on the broken plants.
The end result is that the experts backed up by professionals who track 130-450 animals per year conclude that the tracking shoe without using blood is the 2nd best way to teach a dog.The best being the training on the track of a live unwounded deer.
But it is not only in the UK that it is difficult to change ingrained ideas. A recent meeting in Germany of the Federation of Shooting Dog Societies nothwithstanding being faced with this evidence accepted a resolution that said A blood must be used for trials and B Tracking Shoes cannot be used.
I am looking forward to see my German tracking friends later this year. Guess they will be a bit touchy on this!
