Why Does My Cocker Spaniel Keep Getting Ear Infections? Causes & Prevention

Cocker Spaniels are at higher risk for ear infections, especially in summer when heat and humidity create ideal conditions for yeast and bacteria. Floppy ears trap moisture.

Why Cocker Spaniels Are More Vulnerable

Dog ear infections spike in summer (June-September) when humidity traps moisture in ear canals. Cocker Spaniels' floppy ears cover the ear canal, trapping warm, moist air — creating a perfect environment for yeast and bacteria. Labs are the #1 breed for ear infections nationally. 80% of dogs with seasonal allergies develop ear infections.

What to Do

  • 1.Dry ears thoroughly after swimming, bathing, or rain walks
  • 2.Lift ear flaps weekly to check for redness, odor, or discharge
  • 3.Use a vet-approved ear cleaner weekly during humid months
  • 4.Treat underlying allergies — most chronic ear infections are allergy-driven
  • 5.Don't use cotton swabs deep in the ear canal — you can cause damage

Risks to Watch For

  • Head shaking, ear scratching, rubbing ear on floor
  • Brown or yellow discharge, strong odor from ear
  • Redness and swelling of the ear canal
  • Chronic recurring infections if underlying allergies aren't treated
  • Hearing damage from chronic untreated infections

Cocker Spaniel-Specific Note

Cocker Spaniels should have ears checked weekly May-September. Lift the ear flap and look for redness or smell.

Frequently Asked Questions

Why does my Cocker Spaniel keep getting ear infections?▾
Cocker Spaniels are at higher risk for ear infections, especially in summer when heat and humidity create ideal conditions for yeast and bacteria. Floppy ears trap moisture. 80% of dogs with seasonal allergies develop ear infections because allergic inflammation swells the ear canal, trapping moisture. Cocker Spaniels are allergy-prone, making ear infections a recurring issue during pollen season. If infections recur, treat the underlying allergy — not just the infection.
What months are worst for Cocker Spaniel ear infections?▾
June through September — peak humidity months. September is especially bad for allergy-prone breeds because ragweed triggers ear canal inflammation. Swimming in summer also introduces water and bacteria. Winter is lowest risk unless your dog has year-round allergies.
How to prevent ear infections in Cocker Spaniels?▾
Dry ears thoroughly after swimming, bathing, or rain walks. Use a vet-approved ear cleaner weekly during humid months. Treat seasonal allergies — most chronic ear infections in Cocker Spaniels are allergy-driven. Never use cotton swabs deep in the ear canal.
Signs of ear infection in Cocker Spaniels?▾
Head shaking, ear scratching, rubbing ear on floor/furniture, brown or yellow discharge, strong odor from ear, redness and swelling. Cocker Spaniels may also tilt their head or seem off-balance with severe infections. Catch it early — chronic infections can cause hearing damage.
