They are close to leak proof.

I love these puppy pads! My little foster is able to use the pad more than once and it never leaks or runs. She pees on it and it absorbs right away. The only thing I wish was better are the sticky tabs. They aren't very sticky and she's able to pull them off the floor easily. If that issue was fixed I would feel much better about paying $40 for pee pads lol.

Great Product!

Very absorbing, no smell, I like a lot

I like the pads...help with our make dog who tends to try to scuff them up. But sometimes adhesive pieces stick to floor and have to be scraped off.

Very impressed, great oroduct

These pads are great! They don't leak at all. Sometimes, my pup will have a accidents off the pad, and rather than use a whole bunch of paper towel, I'll take one of these pads, and actually use them to clean the mess, knowing they won't seep through and get on my hands.

Love them

My puppy consistently uses these pads. I think that they are fantastic.

I actually got them for my 16 year old cat who recently decided not to use litter box. At least she uses the bathroom but your pads and many others I have tried do not work. She uses the pads but they all leak thru to the floor? Any ideas?
