My dogs love toys that pay out treats. The Tug-A-Jug by PetSafe is another winner for the small to medium sized dog.
Pretzel, my Cavalier King Charles, drags the medium sized bottle around even after it is empty. The design is simple, a knotted rope in the neck of the bottle offers treats some resistance, so they don't just pour out. Your dog has to tip, tilt and batter the bottle to get treats to fall out. Note, however, if Nemo, my Great Pyrenees, was interested in this bottle it would be dust.
PetSafe claims you can feed your entire dog an entire meal with this bottle. I have two dogs and carefully regulate the amount of food each gets I doubt I'll try.
