I wormed Siggy last month with the normal Ivermectin - the vet has me worming him every three months, but I have not rotated wormers.  I've just been using Ivermectin because it's worked (we did a stool "study" last October and showed that the wormers were working).

Anyway...he keeps rubbing his butt against the fence rail (not something he normally does), so I wonder if the Ivermectin is no longer effective.  Can I worm again, now?  What should I use this time?

Most places you don't have to worm so much but in FLA it don't hurt. Yes I would change every time or 2. Not sure it makes much of a difference it makes what you use.
