Does It Work?
Let's be clear here, no over-the-counter product is going to cure your dog's ear infection or solve his underlying issue. That said, peppermint-scented Espree Ear Care is a nice way to manage the gunk without irritating the delicate ear tissue. Made with tea tree oil, eucalyptus oil, and salacylic acid, it dries quickly and doesn't feel like I'm dumping rubbing alcohol into my dogs' ears.
I've used a few different ear cleaning products both professionally and as a pet owner, and this is my current pick for regular ear care for my allergy dog. However, it does need to be used wisely. This product contains tea tree oil and is definitely not for use in cats. It's also not a great thing to be putting on a perforated ear drum, so it really ought to be used with vet clearance once you've figured out what the actual problem is.
