Our now 12 year old neutered male had an issue with this a few years ago. Our vet performed surgery but said it would unfortunately most likely come back. Well, it’s back and is presently being treated with a medicated shampoo with benzoyl peroxide and topical antibiotic. The skin looks better but theres still swelling in his tail. Wondering if anyone has had this problem? Ive read its typically seen with intact males and that testosterone plays a role. Our guy was neutered at 8 months, but later it was found he had ectopic ureters causing urine dripping/leaking. He then underwent laser surgery to correct it but he needs to take methyltestosterone 3 times a week since age 3 due to weakened sphincter muscle. Any advice would sure be appreciated. This poor guy has also been through double knee TPLO surgeries a few years ago so we dont want to put him through anything else if at all possible. Thanks so much!
