I have Labrador bitch ,that I have been scent training for the last 18 months . I use scent shoes and deer blood . I started off setting a trail 3-4 times a week varying the distance and difficulty . she has tracked live deer but to no great distance ,110m max. I have now cut the training down to once a week . is that enough ? I also have a request that if members dogs do a live deer track please do a write up , as I find these post very informative and interesting .
