Pet Living House Training Puppy Pads with wet indicator are a brilliant idea to help with indoor puppy training. With indicator technology a colour indicator shows when the pad becomes wet. It locks in moisture to prevent leakage to keep your puppy and floors dry. The 5 layer protection helps to keep floors clean and dry. A built attractant is impregnated within the pads to help your puppy find his designated toilet space. The pack contains 30 pads that measure approximately 56cm square.
