A popular item among field and obedience trainers alike. A great way to teach beginning play retrieving without establishing bad habits such as “diving” on the dumbbell. The 2" size is ideal for young pups or for adults in the smaller breeds. The 3" size is for serious field or hunting training. The dummies are filled with air and will float for water retrieves. Orange dummies are less visible to the dog, making them useful for teaching blind retrieves. Do not leave these within reach of an unattended dog—they are not good "chew toys"!
