I have two small dogs that were pad trained when I adopted. I have purchased the PetWorld pee pads for several years. I like the variety of package size offerings and pricing. I have found the large quantity purchasing is convenient and allows me to stock up for the winter months when walking the dogs is not possible. The pads are Not hick for large quantity of urine but they do have a backing that will offer some immediate protection and based on the soiled pad being removed right after use and replaced with new. The key is to not let the pads get soaked with urine and just sit for hours before replacing. If the pad is soaked I would suggest layering more than one pad for extra protection of the flooring. Buying these pads in quantity works out well for pet owners who have a dog that physically cannot be taken out and wearing a belly band is not possible. Even though my two dogs are small, I purchase the larger size pads for the larger dog. The pad is larger which covers more area and I put down a minimum of 6 to 8 pads. Again the key is to layer multiple pads to protect flooring, enough pads for the dog is not limited in space, and finally remove the soiled pads shortly after having been used.
