I have a fat, geriatric boxer, and we've reached the point that she doesn't necessarily wake up from her naps when she needs to pee. Having been down this road with previous elderly dogs, I was prepared with all waterproof mattress encasements, sheet protectors, dog beds, sofa covers, and more. But when laundering all those protective measures became an almost daily thing, I knew I had to do something more.I found out about Washable Wonders via a blogger who raved about them, especially that they're available with no tail hole. I found them here on Amazon when I was looking for the washable pad inserts that were out of stock on the Washable Wonders site, and while I didn't find their pads here, I did find a satisfied reviewer that successfully opted to use Poise pads instead. So I crossed my fingers, bought a big pack of Poise Pads (Ultimate absorbency, Regular length), and ordered 3 of these diapers in the Large size.They're incredible!!! Surprisingly, my dog doesn't mind wearing them at all! The fit is decent, but it looked like they might leak around the legs, so I kept a close eye on her the first night we tried them. Then, when I removed the diaper to take her outside to pee before bed, I realized it weighed a lot more than when I put it on her. Turns out she'd had quite an accident while lounging on the sofa, and the diaper/Poise pad combo completely controlled it! The pad was swollen up and definitely full, but it wasn't wet against her skin, and the diaper held it perfectly in place to do the job. The diaper wasn't even wet, and there wasn't a single spot of evidence on the sofa cover, either! It's exactly the solution I needed, and it's better than I dared to hope for.Since these first 3 I bought worked so incredibly well, I immediately ordered another 4 and have since ordered 5 more. This way I'll have a dozen and can go a bit longer between loads of laundry. Speaking of laundry, these wash well, too. I don't put them through the dryer, per the maker's instructions, so I hang them over the shower rod and they are dry the next morning. My one suggestion to other buyers is to go ahead and get a diaper bin while you're at it, whether it's to hide away unwashed pads or the disposable ones like we use. I bought the Dekor Classic Hands-Free Diaper Pail, based largely on the recommendation from someone who uses Poise Pads himself, and it's been a great way to keep my small apartment odor-free.My only complaint about these Washable Wonders diapers is the color options. For female dogs, they are only available in purple, pastel pink, and lime (they call it avocado) green. For male dogs, though, they're available in black, hunter green, and navy blue, which would certainly be my preference. I'm half-tempted to buy the male diapers for my dog and see if they work for my old girl, but with all the money I've put into the ugly-colored female ones, I'm not ready to take that dive just yet.
