Frequently Asked Questions
My Lab is shaking her head violently and I see blood in her ear — what do I do?
That sounds scary, but stay calm. Blood could mean a ruptured ear drum or a bad infection. Don't put anything in the ear. Gently blot any blood from the outer ear with a clean cloth and call your vet immediately. They'll want to see her today.
How can I tell if it's yeast or bacteria in my dog's ear?
Great question. Yeast infections usually have dark, waxy, smelly discharge (like Fritos or musty). Bacterial infections often have pus, blood, or a strong foul smell. But many ear infections have both. If you're not sure, a vet can take a swab and look under a microscope.
How long does it take for a yeast ear infection to clear up?
With proper treatment — meaning twice-daily antifungal cleaner and keeping the ear dry — you should see improvement in 3-5 days. Full resolution usually takes 7-10 days. If it's not better by day 5, call your vet.
Is it worth going to the vet for a yeast ear infection, or can I just treat it at home?
For a mild, first-time infection, home treatment with a vet-recommended cleaner is often enough. But if it's recurrent, severe, or your dog is in pain, the vet can prescribe stronger medication and check for underlying allergies. The cost of one vet visit now can save you from repeated infections later.
Could my Lab lose her hearing from a yeast ear infection?
That's a scary thought, but it's very rare. Chronic, untreated infections can damage the ear canal or eardrum, which might affect hearing. But if you treat it promptly and follow up with prevention, hearing is almost always fine.
What does a yeast infection look like compared to ear mites?
Ear mites cause dark, crumbly discharge that looks like coffee grounds, and your dog will scratch intensely. Yeast infection discharge is thicker and waxier, with a distinct smell. Mites are more common in puppies. If you see tiny moving specks, it's mites.
