English Cocker Spaniel Health: Ears, Eyes, and What the Records Show

UK vet records show English Cocker Spaniels have more ear and dry-eye problems than other dogs, and fewer allergies. What two studies found, and their limits.

A 2024 study of UK vet records compared English Cocker Spaniels with other dogs. Its plain-English summary says “The results highlight ear and eye problems as key health issues for English Cocker Spaniels that owners and veterinarians should be especially vigilant about.” (Engdahl et al., Canine Medicine and Genetics 2024).

While the breed has real weak spots, the same study found it less likely than other dogs to be diagnosed with several skin and allergy problems. This page sets out both sides, from two studies by the same team.


1. The studies

The data. Both used VetCompass, a database of anonymised UK primary-care records, for 2016. English Cocker Spaniels made up 3.06% of dogs under care (Engdahl et al., Canine Medicine and Genetics 2023).

Two questions. The 2023 study counted what was common in the breed. The 2024 study compared 2,510 Cocker Spaniels with 7,813 other dogs, taking account of age, sex, weight, insurance and practice group.

Funding. The VetCompass work was supported by the Kennel Club Charitable Trust and a pet insurer. Open-access fees were paid by a Swedish university.


2. What was most common

The commonest diagnoses in 2016 were gum disease, at 20.97%, outer ear infection, at 10.09%, obesity, at 9.88%, and anal sac impaction, at 8.07%.

Lifespan. The median age at death was 11.44 years. Only 116 of the dogs studied died that year, so the figures on causes of death are rough.

3. Where Cocker Spaniels did worse

The breed had higher odds of 21 of the 43 disorders compared. The summary says “Disorders with the highest risk in English Cocker Spaniels included ear discharge (14.66 times the risk), keratoconjunctivitis sicca (dry eye, 7.64 times the risk), and musculoskeletal pain (7.06 times the risk)”.

Ears. The authors write that “the pendulous ear shape of the breed is likely an important predisposing factor to otitis externa”. Pendulous means long and hanging.

Eyes. Dry eye is when the eye doesn’t make enough tears. It often needs lifelong treatment.

Our note: The authors describe odds ratios as “times the risk”. For a rare condition the two are close.

4. Where they did better

The breed had lower odds of 11 of the 43 disorders. The lowest were hair loss, atopic dermatitis and allergy in general. Atopic dermatitis is itchy skin linked to allergy.


5. Aggression in the records

The figure. Aggression was recorded in 4.01% of Cocker Spaniels in 2016. The authors say that is almost twice the rate in dogs overall in an earlier study.

Who. It was recorded more often in males than females, and in solid-coloured dogs than in two-coloured ones.

What it means. A note of aggression in a vet’s record isn’t the same as a dog that bites. Vets may record it because a dog is hard to handle at the clinic.

Our note: “What it means” is our reading.

Our note: The 2023 paper says “rage syndrome” has been historically suggested in the breed. We didn’t read the sources behind it.


6. If you have, or want, a Cocker Spaniel

  • Check the ears often, and see your vet about discharge, smell or head shaking.
  • Watch the eyes for redness, sticky discharge or a dull surface.
  • Keep up with teeth and weight, the two commonest problems.
  • Ask a breeder about ear, eye and temperament problems in related dogs.

Our note: These points are ours, including the eye signs.

7. What we could not verify

Commonly saidWhat we found
“Cocker Spaniels are prone to ear problems”Yes, in UK records. Ear discharge had 14.66 times the odds of other dogs.
“Cocker Spaniels have allergies”Not in these records. They had lower odds of atopic dermatitis and allergy than other dogs.
“Solid-coloured Cockers are aggressive”More often recorded, in one study. A record isn’t a bite, and most dogs of any colour had no such record.
“Rage syndrome is common in the breed”Not confirmed. We didn’t read the sources behind the claim.
