About this item SAFE & EASY PET FENCE: The HT-28 wireless pet barrier system includes a transmitter and training collar to quickly and safely train dogs older than 6 mo. and larger than 5 lb. to leave certain parts of your home off limits; after the first or second mild static correction, they will learn to respond to the warning tone alone, protecting your kitchen, nursery, sofa, and more! ADJUSTABLE RANGE: Each fence transmitter leaves your pet free to roam elsewhere while protecting an area as small as 1'4" or as wide as 8'6"; a provided tester tool lets you fine tune everything to meet your needs; when needed, securing multiple areas is as simple as purchasing additional transmitters ADJUSTABLE & WATERPROOF COLLAR: Three metal prongs (0. 8/1. 1/1. 9 cm long) and a training collar that adjusts from 6 to 17 inches in width come included to fit most adult dogs. Make sure you select the proper metal prong to ensure a snug fit for your pet DEPENDABLE SERVICE: The wireless barrier transmitter is powered by 3 AA batteries (not included) but the electronic pet collar works as long as 5 days before being easily recharged from any available USB port or charging station Pattern Dog Brand CO-Z Item Display Dimensions 5. 75 x 1. 57 x 9. 84 inches Closure Type Snap Product Dimensions 9. 84"L x 1. 57"W
