The PetSafe Pet Pager PVPP-300 "Pages" your dog with vibrations. Ideal for deaf or easily distracted pets. Uses vibration instead of static stimulation.  This feature allows you to communicate more effectively.  This trainer can be used not only to get your dog's attention but to summon or let them know to pay attention.  The unit has a 100 yard range. The receiver uses a 6-volt alkaline battery and the transmitter uses a 9-volt battery, both are included. The include owners manual illustrates how to properly use the trainer.

Note: Will work on any sized dog....but is a favorite for toy breeds that may not take well to static correction methods.
