Excellent pee pad tray has "legs" to keep feet off of the pad
Size: 18"X24", Size: 18"X24"
My 10 week old Pekingese learned quickly to use it, and Pekingese are a very stubborn breed. We started training her by removing the grid because she was used to paper. It snaps out easily. We used pee pads with sticky tabs to attach the pad, then snapped the "frame" in place without the grid. Within a few days, she had figured it out, so we snapped the grid back in so her feet never touch the used pad. No more wet feet. I bought the medium size that is aqua blue.
For those that ask if it will fit their crate...measure your crate! My large crate is 42" x 23" and the tray fits two ways as seen in the pictures. My small crate is 23" x17" and the tray does NOT fit. I wish the company made a 10" x 14" tray for traveling. (pink???)
Start using it when you have a couple of days to give your puppy 100% of your attention. 100% attention!!
If she/he does not use it, then it is your fault for not paying attention. My puppy would go every 15 minutes at first! Put a WHITE plastic shower curtain liner on your floor so you can see if she misses it. The liner wipes off easily with Clorox wipes or goes in the washing machine. For those puppies who stand on the edge of the tray, but still miss it because their back legs are barely on it, help them walk forward and put plastic under the tray to catch any misses.
Now, at 4 months old, she seldom uses it, but it is available. Her pen is getting larger and larger. After she pees outside, we let her run around in in the living room for about an hour, then she goes back in the pen. Her attention span is short and she can't always make it back to her tray in the pen. My husband always brings her in the house after she has peed one time outside, but if I take her outside, I wait until she goes at least 3 times and there won't be accidents in the house. Sometimes, it takes more than 1 time to empty their bladder.
This pad tray is not like others on the market. Look closely at other grids, and you will see that other trays do not have the "legs" on the under side of the grid that keep the plastic grid from touching the used pad. My puppy tried to chew on the plastic tray, but she is always in our vision so we just say, "Ahhh!" and she leaves it alone. No problems with chewing. The Ahhh!" stops her every time, and we say it to stop her from doing anything wrong. Some people say their dog chews on it. Just like children, dogs need to be taught. Don't complain about how the pee pad or pee tray doesn't work. Teach your dog or your dog to not chew on it.
Like others have mentioned, my puppy likes sleeping on the tray at night, because it has air circulating under it, so it is cooler than her bed. (Not the fault of the product!) We can't break her of that habit without confusing her or removing the tray. She may stop using it if we teach her to get her off it. I have been putting frozen gel compresses wrapped in a towel in her play pen during the day, and as long as the compress stays cold, she will lay on it instead of the pad tray. Always watch, so a dog doesn't chew on the gel compresses.
I don't know why some people have said that urine runs out, because it is sealed. Maybe they are not changing the pads often enough. I started out changing them twice a day, then since my puppy started flea and tick medicine, she could start going outside. I changed the pad once a day then. Now, at 4 months old, she goes outside, but we put it in her large kennel at night. (The tray is too big to fit in her small dog kennel.) For the last three days and nights, she has not used it at all, but it is there just in case.
If your tray does not have rubber pads on the bottom, buy some or put the tray on a piece of rubber kitchen shelf liner. My tray doesn't slide. If your dog runs to it and jumps on quickly, it may slide, so put something under it.
Remember, your dog may not want to walk on it, but it is up to you to teach the dog to walk on it. They don't get a choice! You are in charge!

Hands down, best pee pad holder
Size: 18"X24"
I did so much research to find the right puppy pad holder. I would give this 10
stars if I could.
It’s softer plastic but not flimsy. The holes are comfortable for puppy feet. I see a lot
with metal grates and pictures of injured doggy feet. Our pups are small and they walk on it just fine. I used to go through 10 pee pads a day. Now one pad lasts all day. Pups can’t go wee wee and trail it all over the house. Since it’s the same pee pad, pups look for the smell and are motivated to pee pee in the same spot. Puppies used to wake up several times a night because they would pee, step in it, tear up the pee pad, make a mess. The night time drama has definitely decreased significantly.
Easy to lock, puppies can’t get into it. Easy to open to change out the pee pad. Comfortable to clean in a larger kitchen sink. Lightweight. Sometimes the doodie will go through the grates and sometimes it sits right on top, depending on the size of the doodie. Cleaning doodie stuck in the grate is never fun, but I use an old toothbrush and it works just fine.
Very happy with this item.

easily destructed by puppy that chews
Size: 24"X24"
disappointed in this purchase. It comes in 2 pieces, which are not exactly easy to fit together and cumbersome. This design flaw also makes it very easy for puppies who are prone to chewing to destroy. It last 1 day then i had to toss it

Great, for the most part
Size: 24"X24"
Love it overall and super glad I chose this one after looking at so many.
Pros:
- Perfect size for what I needed. Fits exactly in the space it was planned for
- Fits 22x22 pee pads nicely (which are easily accessible and cheaper than other sizes)
- the color is a brighter blie than I was expecting and shinier in person, which I like very much :)
Con:
I didn't realize that it's actually 4 pieces.
2 for the top, 2 for the bottom, and you have to put them together.
- I like the little weight distribution pieces they have so it keeps the top from sinking down onto the pee pad.
A few problems with that:
- I'm pretty great at putting together furniture, but for some reason one level connected fine and the other just would not go. I ended up using a flat head screwdriver to pry a piece out so it would go over the other. (If you buy it, you might understand what I mean better lol)
- with it coming in 4 pieces instead of two, it's less structurally sound and tends to bow in the middle. Even more so because they put both middles parallel instead if perpendicular.
- there are potty pads in there, but the seams create a more likely scenario of dripping onto my floor. Where I wouldn't have to worry about that with a solid piece.
- I may have to take the whole thing apart to clean between the individual pieces and this may cause it to be less secure over time due to taking apart and putting back together over time.
Great little thing overall and glad I got it :) serves it's purpose

Works Perfect!
Size: 24"X24"
Same scenario here as a lot of other reviewers... We've got a 10-week-old pup that used potty pads at first... But now is in the teething and let's tear everything up stage. It was starting to get dangerous even with other holders she was tearing up the pads completely and we were worried she was going to ingest them.
We looked at several different products, including the over twice the cost metal wolf brand. But I have to say, really glad we went with this one. It does take a minute to snap together properly, but once you do changing out pads is a breeze.
Once our girl (Mini Poodle) went on top of the greats and used the bathroom we gave her a big reward with lots of praise and a treat. She hasn't been able to tear it up at all. And I believe since she can smell her marking, she has been going back and using it about 7/10 times.
More recently, the success rate has been going up. Like I said, she hasn't been able to flip it over, break it apart etc. So we are incredibly happy with this purchase and has made our lives so much easier.
Once she gets bigger we will see how she handled it. And if she is able to break it apart. But I doubt it, there is a fairly satisfying click when you lock in both sides with the pad beneath.
We are using Frisco pads from Chewy large size and they fit pretty much perfectly. You have to fold the blue border slightly but it works great!
