Why Does My Shetland Sheepdog Keep Getting Ear Infections? Causes & Prevention

Shetland Sheepdogs are at higher risk for ear infections, especially in summer when heat and humidity create ideal conditions for yeast and bacteria. Allergy-prone breeds get ear inflammation from pollen.

Why Shetland Sheepdogs Are More Vulnerable

Dog ear infections spike in summer (June-September) when humidity traps moisture in ear canals. Shetland Sheepdogs' allergy-prone immune system means their ear canals inflame during pollen season, creating conditions for secondary infections. Ragweed season (September) is the worst month. 80% of dogs with seasonal allergies develop ear infections.

What to Do

  • 1.Dry ears thoroughly after swimming, bathing, or rain walks
  • 2.Check ears weekly — redness, head shaking, or scratching are early signs
  • 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

Shetland Sheepdog-Specific Note

Shetland Sheepdogs should have ears checked weekly May-September. Allergy-driven ear inflammation is the root cause — treat the allergy, prevent the infection.

Frequently Asked Questions

Why does my Shetland Sheepdog keep getting ear infections?▾
Shetland Sheepdogs are at higher risk for ear infections, especially in summer when heat and humidity create ideal conditions for yeast and bacteria. Allergy-prone breeds get ear inflammation from pollen. 80% of dogs with seasonal allergies develop ear infections because allergic inflammation swells the ear canal, trapping moisture. Shetland Sheepdogs 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 Shetland Sheepdog 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 Shetland Sheepdogs?▾
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 Shetland Sheepdogs are allergy-driven. Never use cotton swabs deep in the ear canal.
Signs of ear infection in Shetland Sheepdogs?▾
Head shaking, ear scratching, rubbing ear on floor/furniture, brown or yellow discharge, strong odor from ear, redness and swelling. Shetland Sheepdogs may also tilt their head or seem off-balance with severe infections. Catch it early — chronic infections can cause hearing damage.
