It’s expensive, but a little goes a long way towards preventing/remedying ear infections. I still use the first bottle I ever bought and this product has literally saved me hundreds of dollars overs the years. Eko used to get terrible ear infections from his treasure hunting (see below) at the beach and we’d be back and forth to the vet for treatment. After trying countless ear products, this Zymox Otic was far and away the best way to maintain ear health/cleanliness.
