Give your puppy the best chance for success when it comes to potty training. n addition to training young pups, the pads also work well for assisting sick or aging dogs, making dogs more comfortable during transport, or offering an alternative to dogs without timely outdoor access. Each pad comes with five layers to ensure leak-proof performance. The anti-streaming top layer offers a quick-drying quilted surface that locks in wetness, reduces odor, and prevents tracking. The surge layer keeps liquid flowing in the right direction, while the sponge-like core provides maximum absorption and turns liquid into gel upon contact. The last two layers of the leak-proof pet-training pads–the locking layer and the protective plastic lining–keep floors safe from damage.
