My poor dog has issues with her anal sacs getting full and having them expressed about every 3 weeks. Now they are infected. We have done two rounds of antiobiotics. One side looks good, the other still infected. So, the vet infused them today with a steroid/antibiotic. I am worried we will eventually have to have them removed. She is 8 years old and this has become more of a problem over the past few years. Has anyone else had this problem?
