Abstract: There is a training device to train dogs to recongnize an object with a distinctive odor such as a drug like marijuana, heroine, cocaine, and the like. An object with a distinctive odor can be placed in a position that the dog cannot touch or contact the object. Then, the dog is allowed to sniff around the object and if the dog recognizes the object with the distinctive odor the dog demonstrates such recognition. The trainer, at a position remote from the dog and also from the object, can release the object so that it will be available to the dog and the dog can put the object in the dog's mouth or play with the object. The release of the object is a reward to the dog for the dog recognizing the distinctive odor. In this manner, the dog can be trained to recognize an object with the distinctive odor. The distinctive odor may be a drug such as marijuane, cocaine, heroine, or may be another distinctive odor such as the odor of an individual or human being on a search and rescue party.
