For Tate, my only "routine" is to take a soft tissue and "really get in there" to get all the gunk and debris out; i do this about twice a day and he seems like he's in some "nirvana" when i do this to him--he loves it! For Finn, b/c he's had a recurrent tail infection, I use a duoxo + climbazole mousse that I got from the Vet the other day. I just apply some on my fingers and rub into his tail pocket once a day and let it air dry.
