Abstract: To exercise a dog, a tennis ball throwing apparatus includes: (1) an open storage compartment for holding spare items such as spare tennis balls exposed to air for drying the ball; (2) a safety feature to prevent the dog exerciser from being used for throwing small sharp items; (3) a sling arrangement that permits easily throwing of balls a long distance; and (4) an apparatus that permits balls to be picked up without either bending down or touching them with the hands. The balls may be loaded in the storage compartment and later put in a pouch one by one to throw them without touching them. Balls that a dog retrieves may be picked up using the sling without touching the ball and it is automatically put into a storage compartment where it is exposed to air for drying purposes.
