Cocker Spaniel Health Problems: A Complete Guide

Cocker Spaniels are one of Britain's best-loved family dogs, and on the whole they're a fairly robust breed. A large Royal Veterinary College (RVC) VetCompass study found the average lifespan of the English Cocker Spaniel to be around 11.4 years, broadly in line with UK dogs generally. That said, the breed does carry a few predispositions worth understanding before you bring a puppy home, so you know what to look out for and what to ask a breeder.

Ear infections: the number one issue

If you own a Cocker, ears are the thing you'll think about most. Those long, pendulous, hairy ear flaps trap warmth and moisture and reduce airflow into the canal, which is the perfect setup for infection (otitis externa). It's no small problem in this breed: the RVC study found otitis externa affected roughly one in ten Cockers, and the breed was almost 15 times more likely than other dogs to show ear discharge. Signs include head-shaking, scratching, a yeasty or unpleasant smell, redness, and obvious discomfort when you touch the ear.

The good news is that ear care is largely a matter of routine. Check ears weekly, keep the hair around them trimmed, dry them thoroughly after swimming or muddy walks, and use a vet-recommended cleaner if your dog is prone to wax build-up. Catch problems early and most clear up quickly; left alone, ear infections can become chronic and painful.

Eye conditions

Cockers are predisposed to several inherited eye problems. Progressive retinal atrophy (PRA) gradually destroys the retina and leads to blindness; the prcd form can be screened for with a simple DNA test. The breed can also develop hereditary cataracts, primary glaucoma (which is painful and a genuine emergency), and dry eye (keratoconjunctivitis sicca) — the RVC found Cockers were over seven times more likely to suffer dry eye than other dogs. Watch for cloudiness, a red or painful eye, bumping into things, or a sticky, gluey discharge, and get any sudden eye change checked promptly.

Hip dysplasia and joint pain

Like many medium breeds, Cockers can inherit hip dysplasia, where the hip joint doesn't form smoothly and develops arthritis over time. The RVC data also flagged musculoskeletal pain as notably more common in the breed. Keeping your dog lean is one of the single most effective things you can do — obesity was among the most commonly recorded problems in Cockers, and excess weight loads the joints. Sensible exercise, good nutrition and weight control go a long way.

Familial nephropathy and other inherited conditions

Familial nephropathy (FN) is a hereditary kidney disease that typically appears in young dogs, causing the kidneys to fail. Signs include excessive thirst, frequent urination and weight loss, often before two years of age. It is now largely preventable through DNA testing of breeding dogs, which is exactly why buying from a tested line matters. The breed can also carry acral mutilation syndrome and adult-onset neuropathy, both DNA-testable, and Cockers are among the breeds where autoimmune conditions (such as immune-mediated haemolytic anaemia) are recognised, though these are far less common.

The UK health schemes to look for in a breeder

Responsible breeders screen their dogs, and you're entitled to see the results. Under The Royal Kennel Club's recommendations, look for parents tested through:

• BVA/KC Hip Dysplasia Scheme — dogs are X-rayed and given a hip score; lower is better, and you want parents at or below the breed average (around 11).
• BVA/KC/ISDS Eye Scheme, including gonioscopy for glaucoma — ideally tested annually, as some conditions develop with age.
• DNA tests for prcd-PRA, familial nephropathy (FN) and acral mutilation syndrome (AMS), often offered together as the Kennel Club's breed-specific Cocker DNA package.

A Kennel Club Assured Breeder must meet extra health-testing requirements, which makes them a sensible starting point. Always ask to see certificates rather than taking 'they're all healthy' on trust.

When to see your vet

Book an appointment if you notice persistent head-shaking, ear odour or scratching; any red, cloudy or painful eye or sudden change in vision; stiffness, limping or reluctance to exercise; or increased thirst, frequent urination and weight loss (especially in a young dog). Sudden eye pain with a hazy eye can signal glaucoma and should be treated as urgent. Routine annual check-ups, dental care and weight monitoring catch many problems before they become serious — and this guide is general information, not a substitute for advice from your own vet.
