... for dogs as already mentioned in a few recent posts: currently i'm living together with a dog (local breed of hunting dogs, looks similar to a Beagle). my little munchkin shows great promise as a hunting dog -- she has a super nose, is smart and a 30+km jungle walk at 8month old == no problem. however... discipline isn't her strong point so far (she's just one year, so basically still a big puppy and in training); we just returned from our daily beach trip when we had to incidents where she took off on her own , all my calling and whistling being ignored. as i don't like to shout and whistle (==to avoid attention from hominids/ to alert wildlife to my presence) i'm planning to train her to "silent" whistles. has anyone made one?! (i've made "normal" whistles from timber, bamboo, antler, crocodile bone etc. so i know how to do that already) thanks!
