Currently I am advising two of my puppy purchasers on collar condtioning amongst other things. One pup is tough and currently needs high level stimulation which I know will be reduced gradually as she understands what is going on. The other one is shutting down at the lowest possible level and am not sure what to advise - any suggestions would be appreciated. Pups are 12 months old GSPs which is why they are older than the average Lab (much slower maturers).
