Learn to express your girl's bladder. That will help immensely with keeping her hind fur dry and subdue the urine scald. It's not that difficult once you gain some experience. Do you have a vet or friend who can help you locate her bladder by visual palpation?
I wouldn't recommend shaving every fur strand off. You can clip a bit of the excess fur away which'll make it easier to towel dry her after a butt rinse. Disabled Karla had fur entirely shaved away or her fur all fell out from urine scalding ... and it did grow back ...
Having a fur layer, even minimal, will prevent abscess areas from forming, or making her skin even more sore and red. Uncomfortable.
RO Friends : is it bag balm from KV Vet Supply or some Farm and Fleet stores that will help heal urine scald? I apply (and swear by!) SSD (silva sulfadiazine) cream as soon as urine scald appears. Keep applying to the reddened area for about 5-7 days. Then give it a rest. You'll see hair grow back. But it'll be important to express her bladder to keep the urine from staining and acidic effects. Watch so your girl doesn't want to lick the cream all off. karla would do that. ;-) It'll take a short time, but fur will grow back.
Pet Palace bedding is suggested for softness and moisture wicking. It can be tricky if cecotropes get mushed into the lush material. I don't like the way it launders and dries. Nor was it helpful for Karla's movement and limbs. Each bun case is a bit different.... Worth a try however. I put soft (Laura Ashley brand, found at Kohl's stores) bath rugs underneath Karla. The fibers are thick enough to wick away some of her pee output when I'm gone (not at home).
You'll see the rugs in the pics below.
Canon bath rugs sold at KMart might be another option? A soft bath rug with decent fabric blend (and non-skid backing) is better, imo, than towels. Something thicker to absorb pee puddles. Easy to launder. Get a couple on sale ... Look for non-scratchy thickness.
Learning to express her bladder 2 to 3 times a day will bring about improvements if she's less-abled/unable to stand. Bladder expressions will keep urine reservoir from soiling her skin and fur.
Ask for SSD cream from your vet (alternately bag balm though I've got no experience with bag balm. I always use thin layer of SSD when Karla gets urine scald bouts.)
Express her bladder, rinse her butt and legs ... apply the cream ... and tell her she'll be A-OK, ...

If you need help on sanitary pads to keep her knee joints separated and legs dry if she's got physical limitations like Karla, simply ask.
Karla has bounced back many times from urine scald since 2005. Your girl can too!!
hope this helps,
