When you take him in for his check-up, BW, etc. I would like to suggest that you also have him tested for heartworms. They are very prevalent in Florida and I would be concerned since he lived outdoors for a time. Only one can kill. Here is a link to a good article for your vet to read. Dr. Cottrell is in Florida and routinely tests for HWs. Given the condition you received him in, I think I would take him in sooner, rather than later, for a complete workup. http://www.miamiferret.org/heartworm.htm Katharine Florida [Posted in FML 6729]
