Good Afternoon and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
If Fletcher is a cat, the treatment for ear mites is Ivomec, a few drops in each ear will kill them off. This is available at any feed store for cattle. Also, there are feline ear mite treatments available at pet stores that are quite effective. If Fletcher is a dog, ear mites are treated in a similar manner as cats. It is hard to know if this is ear mites or an ear infection so treat with Swimmers Ear, available at the pharmacy over the counter. Apply a few drops of this every 8 hrs and clean out the ears with a kleenex and NOT Qtips.
The pet store also has ear mite medications for dogs but try the Swimmer ear first for a few days. This has an ingredient that dries out the ears so organisms, yeasts and bacteria, cannot grow.
If this is not enough, have your vet examine Fletcher to be sure.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please REPLY so I can clarify for you.
Sincerely, ***** *****
