Four Paws Wee-Wee On Target Trainer is an innovative solution to house training dogs of all ages. The On Target Trainer has patented fasteners to anchor pads in place so your dog cannot move it. It is made of long-lasting, high-impact plastic. The three-sided shape is designed to corral your dog to prevent him/her from missing the pad. No miss, no mess! The side walls can easily be removed once your dog is trained and comfortable using the center of the pad. The On Target Trainer fits standard puppy Four Paws Wee Wee Pads (22" x 23") and includes one free pad with purchase. Although the On Target Trainer uses puppy-size pads, it is suitable for dogs of all ages. Your pet will love having its very own "go-to" place and you'll love that your carpets and floors are protected. If you're looking to speed up housebreaking, the Wee-Wee On Target Trainer may be just the solution you're looking for.
