I've switched to using Shamwow's as peepads this last month, and I like them! They absorb so well and are reusable and good for the environment. I just make sure to put a plastic liner underneath.
Anyways, that may not work with a puppy in training. Missy was fully trained to use the regular ol' blue peepads before I made the switch.
I don't think that any pad is "better" per say, as far as helping your pup to use them more frequently. There are three things that have always helped me to train my puppies. 1)Patience 2)Praise 3)Treats!
