My dog is shaking his head, losing hair, and has itchy spots. Yeast?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 5 years old | 95 lbs

We rescued him in late October. He was treated for ear infections with antibiotics/ear cleaning under anesthesia ($800). We were given ear cleaner and anti fungal ear drops but he will NOT allow anything near his ears. He's on grain free duck food for allergies. He's now started shaking his head frequently. We also noticed lots of hair thinning, and circular missing hair patches/itchy spots. Yeast? Fungus? Ringworm? Are there any tests we should ask for? Should we muzzle for cleaning? Thanks!

Fungal infections and or bacterial infections are possible. Skin testing like hair plugs and skin scrapes are needed to confirm this clinical suspicion. Bacterial colture for ear infection would be appropriate to identify resistant infections. Unfortunately either systemic or local antibiotics treatment are needed. Osurnia (a type of ear drops) can be used as well for not cooperative dogs (administration of it is once weekly). Muzzle should be kept as last resource.
