This is just the cover, you still need some kind of insert. Our dog was dying of bladder cancer, but these would not stay on her no matter what, they kept slipping down off her back but the smaller size was too tight. we ended up having to use gauze to create doggie suspenders to keep them in place. doggie has since passed and we passed these on to a local animal hospital. Our dog was a yellow lab, her hair was smooth and soft, maybe a different kind of haired dog, they wouldve stayed up, or a dog that didnt have such a downward slope from her back to her tail.

My girl is only 23 inches around her waist so we got the XL thinking 24 inches was the biggest it goes, but I think that is where the sizing starts so these ended up being really big on her... unfortunately it leaves a rather large gap and leaks a lot even with pads but I think it would have been okay if we were able to get the correct size, but, honestly, I'm not really fond of the black lining.. it makes it really difficult to see if there is menses on it until you find it is soaked through...I think I will go with a thicker more lightly colored liner for my next purchase.

Just like Chinese made garments for USA humans, these seem to be sized for Chinese dogs. The size I purchased seems to be appropriate for my size dog, Velcro flaps meet in a reasonable place where you'd think they should. A size smaller or larger seems like it would be clearly wrong. But the leg holes are small and seem offset too far forward or rearward and don't coincide with the tail hole. It's not a big, floppy "diaper". It's more like some kind of "Sleek sexy G string for your dog". The ad copy seems to mirror that concept. My dog appears to hate it when I put the thing on her. She won't sit or lie down once the diaper is on. She literally stood against the wall for hours at bedtime instead of lying down. The nylon diaper is stiff and hard. Nothing at all like you'd think a diaper should be.

Essentially useless.

UPDATE: I am not changing the review and still feel the diaper is not constructed properly to absorb urine. But, the seller has read the review, listened to my complaint, and gave a refund. We are using a disposable diaper UNDER this washable diaper. If you have a larger dog the disposable diaper's don't fit properly. Using the this washable diaper in conjunction with the disposable works perfectly. This has solved our issues.

We have a rescued lab that we knew had incontinence issues when we adopted her 4 years ago. The combination of Mocha taking Proin and going out multiple times per day, her incontinence was 99% corrected. If she drank a lot of water, there may be a dribble, but that was rare. After reading the reviews of Proin, we became concerned having our wonderful pet continue with this medication. We began an herbal remedy and knew there was a possibility of leaking. We ordered these washable diapers and began the herbal replacement. Our routine stayed the same and we continued to take her out about every 3 to 4 hours. These diapers are very cute, but useless. What would be the crotch area there is nothing to absorb the urine. The urine leaks when she is lying down, sleeping, or sitting. She has no idea she has made a puddle. We watched as she was sleeping and the urine just ran out the leg hole. There are doggie liners that may work inside the washable diaper and we might try them to see if we add another layer the urine won't leak out the leg hole.

We aren't convinced the herbal remedy will work and will go back on the Proin if we find the incontinence is winning the battle. Our dog has problems sitting in this diaper and does not enjoy wearing it, but we want to give the herbal remedy a wholehearted try. We will buy liners to see if they will help, but without adding a liner, this diaper is useless for our lab.

Cheap shiny nylon outside and sort of weird patterns, but they do the job. Hard to find an XL size and these made our dog comfy and clean.
