Glad for Pets Carbon Activated Training Pads for Puppies and Senior Dogs are made with five layers of strength for leak-proof protection. The activated carbon layer absorbs odor and yellow spots while the polymer layer absorbs and locks in liquid, all while turning it into a gel. The quilted cushion technology prevents the liquid from spreading. These puppy pads use a pheromal attractant, which helps make training your dog a breeze. This dog attractant shows your dog or puppy exactly where to go. These dog pee pads can hold up to three cups of liquid and absorbs in under 30 seconds. These dog training pads are perfect for potty training puppies and dogs, and for senior dogs that need extra assistance while inside. Puppy pads are also effective as a crate liner or dog bed liner and are easy to clean up and throw away once they have been soiled.
