Jewel had a cork screw tail with a tail pocket. We had her tail amputated at the same time as her ACL repair. She was stitched up like a sliver of a moon shape tail level. At one point, it seemed the stitches were casuing some inflammation. We used Neosporin Ointment to help ease the inflammation as well as the itching through the healing process. The stitches were removed two weeks post-op (i.e. 4 weeks ago--my wife casually informed me Jewel is actually 6 weeks post-op as opposed to what I said as 8-weeks yesterday in my update--still a long freakin' time).
So far, there have been no issues and no tail pocket to clean.
