I’ve never heard of an ear cleaning solution clearing up an infected ear. Care to share what product you’re using? My Husky/GSD gets frequent ear infections. We were given a ear cleaning solution to clear the wax buildup before using the medicated antibiotic drops. So 3 days with the cleanser and then 10 with the ear drops. And to use the ear cleanser weekly to help keep his ears clean and clear so if another infection came, it would be easier to go straight to the antibiotic drops.
Honestly, not going to lie, I’d put him in a headlock to clean his ears and put the drops in. He eventually figured out the more of a fight he put up, the longer it took to get it done and finally just gave in. Now he lays down for me when he see solution or drops coming. Lets me do one ear, the flips over so I can do the other.
What makes you think he has an ear infection? Has he had them before? I would recommend a vet visit. They will swab the ear to find out what kind of infection it is so they can provide the right kind of antibiotic to treat it. Not all work for all things.
