Hi, I need to use Maxitrol and Viscotears with Logan, as he has dry eye. I wondered if anyone knew of anywhere I can get this online? My vets seem to charge quite a lot, particularly for the Viscotears, and I need a lot of it as he needs it 4x per day. I don't use the Maxitrol that often,only if he starts getting a discharge as it usually means there is an eye infection, so I'm not too bothered about getting that from the vet. Thanks in advance.
