Hi, I used to have this problem when they were puppies, mostly when they were on Royal Canin, and we found out due to trial and error that Blossom had food allergies to chicken, salmon, corn and grains. We switched her food 4 times before we found one that she tolerated. She would get soft serve poops, pink skin, warm pink ears, red rash on her chin, and itchy paws which she would lick a lot. After we got her on a food that didn't cause these issues, her poops improved, they are firm but soft, and she goes twice a day. Nether one of my guys have a tail pocket, or a cork screw tail, so we don't have any issues with that, and since their poops are solid, we don't have any poop on them when they go. When we did have the soft poops, we used unscented baby wipes to wipe their bums after doing their duties.
