Four Paws Wee-Wee Pads were developed over 35 years ago to help pet owners housebreak their puppies. Today it is the # 1 selling housebreaking pad in the world! However, Wee-Wee Pads are used for far more reasons than just housebreaking a puppy. Wee-Wee Pads offer more freedom and an easier life style for pet owners. No longer do you have to rush home to let the dog out or if the weather is bad, just use a Wee-Wee Pad. Great for older pets that have a problem with bladder control.
