How long does it take for a dog's ear infection to go away?

You’ve probably noticed your dog scratching their ear nonstop, shaking their head, or even whimpering when you touch it—and wondered how long this discomfort will last. Ear infections are common, but that doesn’t make it easier to watch your pup suffer. It’s normal to feel anxious about their pain, and asking “how long?” is one of the first steps to helping them heal.

The first thing to know: no two ear infections are the same, so recovery time depends on what’s causing it. A quick trip to the vet isn’t just a good idea—it aligns with local animal welfare guidelines that prioritize your pet’s health. Vets can tell if it’s bacteria, yeast, or something else (like allergies) and prescribe the right treatment. Skipping this step might make the infection linger, so don’t put it off.

Mild infections treated with prescription ear drops often clear up in 1 to 2 weeks. But if it’s more severe—like if the infection has spread deeper—or if your dog needs oral meds, it might take 2 to 3 weeks. Always follow the vet’s dosage exactly; stopping early, even if your dog seems better, can make the infection come back. This isn’t just about healing fast—it’s about doing it right.

Home care plays a big role too, but stick to what your vet recommends. Wiping the outer ear with a damp cloth (never cotton swabs deep inside!) can help keep it clean. Avoid getting water in their ears during baths—many owners use ear covers for this, which is a simple habit that prevents future infections. Also, if your dog has floppy ears (like Cocker Spaniels), check them weekly for redness or odor.

Keep an eye out for signs that things aren’t improving. If your dog is still in pain after a few days, or if you see discharge, swelling, or hearing loss, call the vet right away. Some infections need adjusted treatment, and waiting can lead to more serious issues. Your attention to these small details makes all the difference in their recovery.

Watching your dog heal from an ear infection takes patience, but seeing them stop scratching and start acting like their playful self again? That’s the reward. By staying on top of vet visits, following treatment closely, and keeping up with simple care habits, you’re giving them the best chance to feel better fast. Your pup can’t tell you when their ear hurts—but they’ll show you when they’re back to normal, and that’s worth every minute of care.
