The Vibrant Life training pads are designed with 5-layer structure to effectively absorb and lock in dog urine, prevent leakage and keep the floor clean and hygienic. The top layer dries quickly which can prevent wet paws tracking. Each pad can hold up to 2 cups of liquid, and contain odor neutralizer to effectively absorb odors, making your room free of odors. The pads have built-in attractant to helps the dog know where to poop, making training easier. These Large size pads 22" x 22" are ideal for toilet training of puppies, daily use of small and medium sized dogs, and elderly dogs with no mobility. Simply unfold and place the pad with the blue plastic side down, in a confined area, away from your puppy's food and bed. Place your pup on the pad a few times so he can smell it and get used to it. If he happens to relieve himself elsewhere, bring him back to the pad immediately to reinforce that the pad is the place for the soil. When your good boy relieves himself on the pad, praise him and be sure to reward him with a Vibrant Life treat.
