My Mack is 4 and according to our vet has the tightest cork screw tail he has ever seen. He has only had an infection twice in his 4 years, once when he was 12 weeks old and I didn't know any better and when he was 2 and I had to go away. If Mr Beefy's tail is infected now he needs to be on an antibiotic and you may need to clean the pocket 2 or 3 times a day till it's cleared up. When Mack's was infected I would stand him the tub and wash it out with warm water, you have to really get inside the pocket to make sure you get everything out. To do this I use an ear or nasal ball that they use on babies to clear their noses. Mine has a very narrow end so I can really get it in there, just suck warm water up into it and flush out the pocket. Then you have to make sure you dry it out very very good I use the square facial pads and q tips to really get in there. I never use any kind of ointment or anything like that on his pocket as it only adds to making the problem worse. I clean his tail pocket daily I flush it out with warm water and then dry it. Once i dry it out I have wipes from Glen Haven products that have medicine in them for yeast, I then wipe it all out with a wipe so nothing gets started in there. These wipes are great the medicine is very drying to so that helps a great deal. I use the F3W F is for fungus, the 3 for the strength and the W for wipes. Go to Glen Haven's web site they charts that show you all their products. I swear by their stuff don't know where I would be without them, Mack probably wouldn't have a tail. Please try this for Mr. Beefy as my vet said unless it's infected all the time you really do not to amputate his tail. To many small veins and things that go to other places. let me know if I can help in anyway.
