Cellulitis can take a long time to fully heal - sometimes up to a month or more. Occasionally, the infection is so bad that the inflamed tissue needs to be surgically removed. I would not be too worried yet if it's less than two weeks of treatment. Your vet will be able to give you a good idea on how well the condition is improving and if anything else is needed on his next recheck.

I hope that helps and all is well with Trick.
