I need to keep my dog's ears clean to prevent him from developing infections, however, his skin is sensitive. This is one of the only products I have tried that does not irritate his skin. This product has a very mild fragrance. DVM brand also makes a clear solution with no fragrance called Oti-Calm that my vet perscribes which is also non-irritating, however, Alocetic seems to be more effective for preventitive care.
