It doesn’t stop leaks from the pee pad.
Size: X-Large: 28" x 34"
I’m trying to figure out how not to have leaks occasionally. I’m going to call the company to see if there’s something I should be doing.

FANTASTIC PAD HOLDER
Size: 28'' X 34'', Size: 28'' X 34''
Amazon Basics Dog Training Pad Holder 28X34. I'll start out by saying I wasn't too sure about it, when I got it. It is awkward to put the pads in by yourself if your short as on each end the sides have to come up together and it’s big, however, I've done it five times alone now and it’s doable. There was no smell, it arrived in perfect condition. My husband was home and we set it up together, I walked into the bathroom to get a soiled pad I had keep to put on it for her to know what to do came back and she had already used it and she’s only four months old. I love it love it love it, it’s not too big, but it’s her home too, and we have it in the living room where we spend a lot of time as we’re retired. When she gets a little older, we will probably move it to another room, but for now it’s staying there. After she urinates, it goes down to a very pale yellow color I have been able to use one pad for all day, however, she does have a pad in a under bed tote in our master bathroom. We’ve had a few guests over and if she hadn’t used it they didn’t even know what it was. I highly recommend it. I have been using pads in an under the bed tote for over 10 years and this is a welcome audition. You won’t be sorry if you have little ones that go in the house.

Very easy to use and clean
Size: 22'' X 22''
Saved my pad training with my puppy. It's firm and easy to clean. It holds the pads well for the most part, but sometimes my dog gets a little crazy and it comes out, but I don't think it could be better. Still give a 5-star!
