Hi Lisa
Persistent anal gland infections can take a while to treat and heal and sometimes there is scarring from previous infections present which slows the healing. At the very least I would recommend very regular anal gland emptying in a case like your dog. Empting them before they fill up, and get another infection and risk of an abscess can help. If this keeps recurring and cannot be cleared, surgical anal gland removal is a possible next step. You should discuss all that with your vet. Every vet sets their own fees. I dont know where you live but those fees sound reasonable to me. Many vets charge a fee for each examination, that is certainly our policy here.
