What are paua sniffer dogs?

Allot of dogs are trained by first having the correct substance, in my case bed bugs, in a plastic container place it in the middle of a big room or in a forest or field put a leash on the dog take him to it let him sniff it with the lid off then give him a treat or biscuit that he likes. then take him back let the leash go and then if he doesn't go directly to it take him to it (don't get frustrated with the dog if this dog isn't a puppy it will be hard to understand) continue to do this about four times a week for two weeks. Then, take the usual plastic container and hide it not somewhere hard but maybe just in the corner or behind a tree and have him find it do this for another two weeks then add like three or four more containers they can contain old shirts or cotten ball's nothing to distracting and re hide all the containers in new spots have him try to find it by now you need to pick a command before letting him go say a Word of your choice make sure it doesn't sound like any other command do this for two weeks now for the last session you will take him to a new place such as a park with other scents put the containers in new spots add new containers with things such as different treats fruit slices or there favorite toy add as many as you like the more the better but remember there will be other scents if it is public. Have him find it do this three times per week for about tree weeks or until he gets it. Now that he is trained start looking on the internet or news paper for a job then call them to schedule an appointment all while still taking him to the park about once a week to train.
