Our RUFFIN' IT™ Lil' Squirts training pads are all engineered to provide 12 hr of protection, with capacity to spare! That's because these pads are built with our ULTRALOCK absorbent CORE, with capacity to lock in over 3 cups of urine. That is over 2x the average amount a 50 lb dog would eliminate in 12 hrs. The extra large pads are 80% larger than standard pads and are ideal for larger dogs or multi-dog homes. Our new Lil' Squirts odor control pads have an activated charcoal odor neutralizer that eliminates odors instantly.
