Ear Infections: Why They Keep Coming Back
Treating each flare is not enough. Recurrent ear infection means an underlying cause - usually allergy.
The cycle
Underlying allergy -> ear inflammation -> moist environment -> bacterial/yeast overgrowth -> infection.
Breaking the cycle
- Diagnose underlying cause (allergy workup)
- Maintenance ear flushing - vet-recommended cleaner weekly or fortnightly
- Allergy management (food, atopy, fleas)
- Address ear anatomy if relevant - heavy ears, hairy canals
Signs of an ear flare
- Head shaking
- Scratching at ear
- Tilting head
- Bad smell
- Discharge
- Pain when touched
Properly treated, most recurrences are preventable. Book an ear check-up if your pet has had >2 infections this year.
Frequently asked
Most dogs - fortnightly. Floppy-eared and swimmers - weekly.
