Hello! Our vet recommended us to use cotton swabs to clean our 20 week old puppy's ears daily. (He doesn't like the solution method for some reason.) However, he is not getting used it at all and gets so aggressive when we hold him to put the cotton swabs down. (We got bitten multiple times to the point when the bite marks are bloody.) So, we are thinking of switching to the solution method and clean it twice or three times a week. Do you guys recommend cleaning the ears regularly with solutions and can you recommend a solution product for the ear cleaning? Thank you!!
