Sorry to hear about your friends cocker Wendy
... insurance company don't sound like much cop
(do you know who she's with?)
Purdey was on Optimmune but also alternated between Lacrilube & Viscotears too. She's now prescribed Maxitrol which, for her, has worked brilliantly & is (paws crossed
) problem free! We don't have any problems with insurers & are able to claim but have heard that it is possible to order online at much cheaper prices ...
(......... however, my only concern with that is, that, some weeks ago I watch a programme about drugs being ordered over the net & although they came with all the correct instructions & in the right packaging, when they were tested, they didn't have the correct content they should have & were in fact quite dangerous!.... but that's just me being over cautious
Sometimes though Wendy, after a course of treatment the tear ducts can right themselves & start working again or work intermittently - hope this is the case for your friends dog & as Mel says, diet may/can help too
