Dolores If horses can scent a person could scent training retrieve work? A good friend of mine wrote an article that was in the IAADP Partners Forum, its not on their website as those are older editions. The concept was to train a scent using some sort of scent pouch you can attach to item. Don't use scents that she would regularly smell in cooking and general life but ones specifically chosen. First teach the scent so she has it down pat, then you attach the scent to the item such as a phone for instance. What my friend learned with her service dog is that the accuracy of the retrieve was far better than without the scents. Obviously you don't want to use scents you will get sick of and you may have to replenish at times depending on the scent of choice, but it is an amazing concept. Karyn and Thane
