My dog has dark ear wax, coffee grounds. Ear mites? OTC treatment?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 7 years and 1 month old | 9999 lbs

So, my 7 year old, chihuahua shitzu mix has a thick dark brown almost black looking wax coming our of one ear and there are coffee ground spots in there too. Is it ear mites and if you can't diagnose him online, what is the most effective ear mite treatment i can get without a prescription?

It could be ear mites, and unfortunately I can't diagnose Peaty online because I can't see him in person or examine the wax coming out of his ears. Revolution treats ear mites, but I do highly recommend a vet visit for this problem. This is because ear infections in dogs can also be caused by yeast or bacteria, and in order to treat him properly, the cause needs to be diagnosed. I certainly don't want you to spend money on a treatment that ends up being ineffective because it isn't the correct medication for the ear infection (Revolution does not treat yeast or bacterial ear infections). I would make an appointment for him to be seen by a vet for this problem so it can be treated correctly the first time. Best of luck.
