A retrieving device includes a body with at least one respiratory passageway formed in it through which a dog can breathe when holding the device in its mouth during retrieval. In some embodiments, the body is hollow and in the form of a shell defining an internal cavity that functions as a lateral respiratory passageway, with communicating respiratory passageways formed through the shell. In other embodiments, the body is solid with internal respiratory passageways formed through it. And in still other embodiments, the body has surface features (e.g., grooves or other thinned portions) that function as external respiratory passageways. In use, the respiratory passageways decrease obstructions to enable the dog to breathe more freely to avoid overheating and associated problems. In addition, one or more flotation elements can be provided in the body so provide buoyancy for the retrieving device in the event its launched into water during retrieving activities.
