Dr Aimee Warner, resident vet at UK pet insurance company Waggel, has warned dog owners not to ignore early signs of ear infections, which can cause serious and long-term health issues if left untreated. She says behaviours like head shaking, scratching, or mild odour are often overlooked.
“Many owners dismiss the early warning signs of ear infections as normal dog behaviour,” said Dr Warner. “Head shaking, ear scratching, and even a mild odour can be easy to normalise. What’s concerning is that untreated ear infections can lead to chronic pain, hearing loss, and in severe cases, require surgical intervention. The difference between early intervention and delayed treatment can mean months of unnecessary suffering for your pet.”
Research from the Royal Veterinary College shows some breeds are more at risk. Basset Hounds are 5.6 times more likely to develop ear infections compared to crossbreeds. Labrador Retrievers, Golden Retrievers, and Cocker Spaniels also show a higher risk. Dogs with pendulous ears or hair-filled canals are particularly vulnerable due to reduced airflow and increased moisture retention.
Symptoms often start subtly, with occasional head shaking or scratching. As infections worsen, dogs may develop redness, swelling, discharge, odour, and discomfort. By this point, infections are more complex to treat. Recurrence is common unless underlying causes – such as allergies, swimming habits, or breed-specific anatomy – are addressed.
She advises regular ear checks, using only vet-recommended cleaning products, especially after bathing or swimming. Owners should not use cotton buds inside the ear canal and should consult a vet at the first sign of discomfort. Preventative care may be needed for high-risk breeds or dogs with recurring issues.
“Ear infections represent one of the most treatable yet persistently common health issues in dogs,” Dr Warner said. “Early intervention can mean the difference between a simple course of medication and months of chronic, painful infection. Many owners are shocked to discover how much their dog’s behaviour and happiness improve once an ear infection is properly treated – dogs they thought were ‘just getting older’ suddenly become more playful and energetic once that constant discomfort is relieved.”
Dr Warner’s practical tips to prevent and identify ear infections:
• Regularly check your dog’s ears—healthy ears should be pale pink, odourless, and relatively clean
• Clean ears gently as recommended by your vet, especially after swimming or bathing
• Never use cotton buds deep in the ear canal; use vet-approved cleaning solutions instead
• For dogs with floppy ears or known susceptibility, establish a regular ear-checking routine
• Address underlying allergies with your vet’s guidance, as these frequently contribute to ear issues
• Learn the early warning signs: increased ear touching, head shaking, or redness
• Consider preventative ear cleaning for high-risk breeds, but only with products recommended by your vet
• Seek veterinary attention at the first sign of ear discomfort rather than waiting for obvious symptoms
