I have been using Sancerum ear cleaning drops in Emma's ears for some time now with little effect, she makes this dark brown waxy kind of gunge, it doesn't smell, doesn't irritate her, but sometimes seems a bit gluey. We have taken her to the vets several times for ear infections in the past and I'm reluctant to take her back as she gets very distressed, upset and has to be muzzled. The vet advised using Sancerum twice a week to keep her ears clean, but it's not working, I also use wipes daily to gently clean the skin area in front of the ear hole.
