You're speaking with Dr. Michael Salkin. Welcome to JustAnswer. I'm currently typing up my reply.
I'm sorry to hear of this with Daisey, Sean. The first thing to do is to stop expressing her anal glands. This is done far too often as a matter of course and in most cases is not only unnecessary but aggravates and damages those anal sac glands thus encouraging even more odiferous exudate to be produced. Here is what I would do:
Empty the glands once more but follow up with flushing each gland with an antimicrobial solution such as chlorhexidine. This is done with a curved tip syringe and most dogs will allow this procedure without their being sedated. Once thoroughly flushed, another curved tip syringe filled with an antibiotic/antifungal/antiinflammatory ointment such as one we would use in the ears is then used to pack the glands with the ointment. This should address any infection/impaction that has precipitated the recurrent odor. Then leave the anal glands alone and see how this treatment works.
Please respond with further questions or concerns if you wish.
