My baby had ear mites as well when i took him home. The vet suspected it when she done a ear swab. She confirmed it by looking under the microscope. So she gave us eardrops for the dog twice a day and he also done 2 rounds of revolution (1 month between each round), she also gave us a ear cleanser for every other day until he was fine again. When she first checked him he had adult mites, after one round of revolution and eardrops and cleanser she checked him again and he only had eggs at that point. So like i said after second round of revolution he was good.which made me very happy!!!!
