Why does my puppy have a snout rash and itchy ears after Revolution?

Updated on September 23rd, 2025

Pet's info: Dog | American Pit Bull Terrier | Female | unspayed | 4 months and 16 days old | 29 lbs

Hello. I have a female 4 month old blue nose pit bull. She has a rash in her snout and is also pulling and itching at her ears often. I just applied a dose of Revolution flea and mite treatment yesterday. Are these symptoms related to the ear mites? Or is this something else?

In dogs, itching at the ears is a sign of an ear infection, but those can be caused by yeast or bacteria in addition to ear mites. There's no problem giving Bella the Revolution, as she needs protection from fleas, but have her seen by the vet for scratching at her ears to make sure this behavior isn't caused by bacteria or yeast. The vet can also check out the rash on snout, which could be caused by an allergic reaction. Give your vet a call today to make an appointment for her. Best of luck.
