I use a solution of alcohol and white vinegar. Definitely don't use plain water....if it gets into the ear it can cause an infection.
Yeah I was thinking alcohol- ouch. I could maybe see using a little on healed ears to get glue or something off but not as an antiseptic- so many other things out there.I suggest using a half white vinegar and half water solution for cleaning ears throughout your pups lifetime. It will help prevent yeast infections and does no tissue damage. I use a cotton pad with the solution on it to wipe out ears. I wouldnt use peroxide or alcohol as they sting very badly and cause tissue damage at the cellular level.
