Why Does My Cavalier King Charles Spaniel Keep Getting Ear Infections? Causes & Prevention

Cavalier King Charles 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 Cavalier King Charles Spaniels Are More Vulnerable

  • 2.Lift ear flaps weekly to check for redness, odor, or discharge
  • 3.Use a vet-approved ear cleaner weekly during humid months
  • 4.Avoid getting water in ears during baths
  • 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
