I can give you advice on how I maintain my Samson's tail but not what to do in that situation because luckily for me my routine obviously works because we've never had any issues with it. My Samson has the inverted/screw tail, it was discovered by our vet when he was about 8 months old (he's almost 6 yrs old now). I had taken him in because he kept scooting his booty on the carpet and an anal gland expression hadn't helped. They told me to clean it with the fort dodge waterless shampoo and follow it with mal-a-ket wipes (both can be given by your vet or you can get them on amazon). They said if it ever got infected they could possibly have to amputate it but like I said, never had any issues. I just use those products to clean it several times a week. My vet also prescribed neo predef powder for his irritated facial wrinkles and said it works great for tail pockets too. I haven't tried it on his tail but it does work wonders for those facial wrinkles so it may be worth a try as well. The neo-predef powder has to be prescribed by a vet but once you get the prescriptions I suggest getting your refills from somewhere else, for instance I get my refill from Dr Fosters & Smith and its WAY cheaper than what they charge at the vet. Hope that helps! Good luck!
