Built with Glad level durability and leak-proof protection, Glad for Pets Dual Action Freshness Activated Carbon Puppy Training Pads are great for training new dogs and making it easier on senior dogs, as well as for carrier and crate liners. Our signature black charcoal pads not only hide unsightly yellow spots, but the activated carbon technology neutralizes odors from pet urine and waste. Plus, these pads have a dual action odor-masking technology: when the pad is used, microcapsules target odor-causing ammonia in pet urine, then release an extra burst of fragrance. Glad activated carbon training pads for pets are made with six layers of leak-proof protection, plus unique folded edges for extra leak resistance. The gray quilted top sheet helps stop liquids from spreading. The carbon tissue layer neutralizes odors and masks yellow spots. The ultra absorbent polymer layer turns liquid to gel in just 15 seconds, keeping your pup's feet from tracking through the house! These 23”x23” pads can contain up to 4 cups of liquid, and the leak-proof PE liner protects floors from any seeping moisture. Additionally, Glad training pads include an odorless pheromone attractant that encourages dogs to mark the right place right from the start. These disposable pads make potty training a breeze, and when they've been used, simply discard them and replace with a fresh pad. Glad has always been the go-to brand to conveniently contain messes, and pet parents know that few things make bigger messes than pets. From potty training to waste clean-up, pet parents need a brand they can rely on for leak-proof, durable, convenient, & effective clean-up solutions. *It is recommended to keep edges folded for additional leak protection. Dimensions with folded edges are 20.5" x 23" (52.07cm x 58.42cm).
