NO GO!
Color: Dark Gray, Size: 22" x 22"
I was really hoping this would work, but it did not. The minute I put the tray down with puppy pad secured, my puppy managed to chew and dig at the edges ripping the pad away from the side of the tray and making a huge mess! I am not returning it bc this company makes you take it to UPS which is not convenient for me, so maybe I will donate it. If your puppy is massive chewer this may not be the thing for you.

Great idea.
Color: Dark Gray, Size: 22" x 22"
Great concept! Unfortunately, the plastic area underneath the pad area isn’t very thick and flexes. When my dog used it the first time the plastic flexing up and down under her feet frightened her a little bit. I placed a rubber mat between the pee pad and the flimsy plastic and that stopped the plastic from flexing but since it scared my dog from the first use she won’t go back on it.

PERFECT PEE PAD HOLDER: AFFORDABLE, EASY TO CLEAN & CHANGE THE PEE PADS, HOLDS PADS IN PLACE
Color: Navy, Size: 22" x 22"
I was THRILLED when we finally received it! I had been everywhere on Amazon & some other sites. I almost bought one that had a small pole since my newly adopted Chihuahua actually lifts his leg, unlike my previous male Chihuahua. But I kept running into a lot of holders that had a plastic "grill" to pee through the pad underneath. It didn't seem like it would be easy to clean. Plus, they were VERY expensive. However, I somehow came across this one. Once I saw the picture, it caught my attention. I watched the video & read more about. The only problem I remember is the video showed one that's foldable & easy to take anywhere with you. But that wasn't the case when we received it. However, I was still very happy with it. The only thing I wasn't crazy about was having to change pee pads because of the size. I changed to Earth Rated because that's what was recommended for this holder. My Chihuahua is around 5 years old & was "housebroken" before I adopted him from a shelter early last year. We live in an apartment on the first floor. But can't always run out the door when he has to go potty. He can wait, but I simply can't drop everything I'm doing to take him outside & I don't want to keep him waiting. He wouldn't really use it at first. But he finally got the hang of it. It's very convenient for him. I bought it primarily because I can't always go outside. Yet, it's perfect when it's raining & neither of you can't go outside, it's great to have when it's not safe to go outside in this area. I bought this around Black Friday week & got it for half its regular price! I'm thinking of getting another one to give him more space (sometimes he misses & accidentally sims for the floor). I've been cleaning it every time the pad needs to be changed. I use Biokleen Bac-Out for Pet Stains & Odors - Lavender Lime scent, which works great, but it's too expensive on Amazon. Also Earth Rated pads don't seem to work well with minimizing odors. I also find it a bit difficult to see if my dog peed because the bottom color is green. But they fit well & have adhesive corners. My dog never chews on the pads. The only problems he has is that he likes to push & pull the pad like dogs do to the grass outside when they finish peeing or pooping. Also, I don't know if the holder we have has non-slip small parts on the corners underneath. So since the floor is laminate & maybe has gotten more slippery from cleaning with the Enzymatic spray cleaner I use, the holder has been slippery lately. In the meantime, I'll try out the 100 pee pad pack sold by Iris, the maker of the holder. The previous pads don't have pads in the right size. I'm referring to Hartz 24 Hour Miracle Pee Pad in Lavender. They're white, but very absorbent & the best part: they help neutralize the odors.
I absolutely recommend this pee pad holder! We got the Navy, 22" x 22", which was on a HUGE sale for HALF ITS PRICE! It's too bad I didn't buy two! It's easy to take apart (the top from bottom) to clean. The handles that latch down & the design do a good job of keeping the pads in place. If only I can find pads like Hartz, I wouldn't have to change the pads so much lately. Although I LOVE the Enzymatic cleaner Biokleen Bac - Out for Pet Stain & Odors in Lavender Lime, I'm getting tired from cleaning. But hopefully when it gets warmer here in Florida, it'll get easier again. My dog is really wonderful! I bought this NOT to be lazy, but to give him a happier, more comfortable life. He seems to be happy to have the convenience of the pee pads & enjoys watching me clean!

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.

Great for smaller dogs
Size: Small
These two balls are perfect for the smaller mouthed dog that loves to play fetch.
These balls are not only super durable (lots of teeth biting), but float in the baby pool we use for our miniature dachshunds.
The value here is much better than you’d find anywhere else. The noise, if bitten hard enough, was “low” at best. Easy to spot/find if overthrown. Will definitely buy again once these are in bad repair; so far, so good-love these for my fur babies!
