Health overview — what to know as a Cocker owner
English Cocker Spaniels have a life expectancy of 12–14 years and are considered a relatively robust breed. However, several conditions appear at a significantly higher rate in Cockers than in the broader dog population, and knowing about them in advance is the difference between catching something early and facing an expensive, distressing situation later.
The conditions in this guide fall into two categories: those that are almost inevitable (like ear issues) and those that are breed-predisposed but not universal. Understanding both helps you set the right expectations, maintain the right preventative habits, and know when something warrants a vet call rather than a wait-and-see approach.

👂 Ear problems — the number one Cocker health issue
If there is one health issue that defines the Cocker Spaniel experience for UK owners, it is ear problems. The breed's long, heavy ears hang down and cover the ear canal, drastically reducing airflow. The result is a warm, moist environment that is almost perfectly designed for bacterial and yeast overgrowth.
The condition is called otitis externa — inflammation and infection of the outer ear canal — and it is the single most common reason Cocker Spaniels visit UK vets. UK claims data puts the average treatment cost per episode at £819, and many Cockers suffer recurring infections throughout their lives.
Otitis Externa (Ear Infection)
What it is: Inflammation and infection of the outer ear canal, caused by bacterial or yeast overgrowth in the warm, airless environment created by the Cocker's pendant ears.
Signs to watch for: Head shaking, scratching at ears, redness or discharge inside the ear flap, strong or unusual smell from the ear, yelping when the ear is touched, tilting the head to one side.
What to do: Mild cases may resolve with ear cleaning drops from your vet. Moderate to severe cases need prescription ear drops, sometimes oral antibiotics. Chronic recurring cases may require investigation of underlying causes (allergies, anatomy) and occasionally surgery (TECA — total ear canal ablation) in the most severe cases.
Prevention: Weekly ear checks, keeping ears dry after bathing and swimming, regular ear hair removal (ask your groomer), and a maintenance powder such as Thornit. Never poke cotton buds into the ear canal.
⚠️ Ear emergency — see a vet same day if:
- Your Cocker is in obvious pain when the ear is touched
- There is blood or dark brown discharge coming from the ear
- The dog is holding their head at a persistent angle (head tilt)
- There is swelling of the ear flap itself (aural haematoma)
- The dog is distressed, off food, or has a temperature
👁️ Eye conditions
Cocker Spaniels are predisposed to several eye conditions, some hereditary and some mechanical. Regular eye checks — both at home and at your annual vet appointment — are important for catching problems early, when treatment options are widest.
Progressive Retinal Atrophy (PRA)
What it is: A group of inherited conditions causing the photoreceptor cells in the retina to deteriorate over time, eventually leading to blindness. In Cocker Spaniels, the most common form is CORD1 (cone-rod dystrophy), which typically begins with night blindness and progresses to full blindness, often between the ages of 4 and 8.
Signs to watch for: Reluctance to go out in low light, bumping into things in the dark, dilated pupils in normal light, apparent clumsiness. The progression is usually slow — many dogs adapt well if their environment remains consistent.
What to do: There is currently no treatment for PRA that halts progression. Management focuses on keeping the dog's environment consistent and familiar, using scent markers, and avoiding unnecessary furniture rearrangements. Some dogs live full, happy lives despite significant vision loss.
Prevention: DNA testing of breeding dogs can identify carriers and affected dogs. When buying a puppy, always ask for proof that both parents have been DNA tested clear for PRA. The test is available through Laboklin and Animal DNA Diagnostics in the UK.
Cataracts
What it is: Clouding of the lens of the eye, which can be hereditary (appearing in younger dogs) or age-related (appearing in older dogs). Cocker Spaniels have a higher incidence of hereditary cataracts than many breeds.
Signs to watch for: A visible bluish-white cloudiness in the eye, increasing clumsiness, apparent difficulty seeing in dim light, reluctance to navigate stairs or unfamiliar environments.
What to do: Surgical removal (phacoemulsification) can restore vision in many cases and is performed by specialist veterinary ophthalmologists. The procedure costs £2,500–£4,000 per eye in the UK. Not all cataracts require surgery — your vet will advise based on the degree of visual impairment and the dog's quality of life.
Glaucoma
What it is: Increased pressure within the eye that damages the optic nerve. In Cocker Spaniels, primary glaucoma (where the condition arises without another underlying cause) occurs at a higher rate than in most breeds.
Signs to watch for: Redness of the whites of the eye, a visibly enlarged eyeball, cloudiness, squinting, or pawing at the eye. Glaucoma can be acutely painful. In severe cases it develops rapidly — this is a veterinary emergency.
What to do: Eye drops to reduce intraocular pressure are the first-line treatment. In severe or unresponsive cases, surgery or removal of the eye (enucleation) may be necessary to relieve pain. Early diagnosis significantly improves outcomes.
🐾 Skin & allergies
Cocker Spaniels have a higher-than-average incidence of skin conditions, many of which are allergy-related. The breed can develop sensitivities to food ingredients, environmental allergens (pollen, dust mites, grass), and contact allergens (certain fabrics, cleaning products). Skin problems are often chronic and require long-term management rather than a one-off treatment.
Atopic Dermatitis (Environmental Allergies)
What it is: A chronic inflammatory skin condition triggered by environmental allergens. In Cocker Spaniels it commonly presents on the paws, belly, groin, armpits, and around the face and ears.
Signs to watch for: Persistent licking of paws, scratching, red or inflamed skin, recurrent skin infections, hair loss in affected areas, a musty or yeasty smell. Symptoms often worsen seasonally (spring/summer pollen season) or year-round if house dust mites are a factor.
What to do: A vet referral to a dermatology specialist is worthwhile for chronic cases. Treatment options include antihistamines, essential fatty acid supplements, medicated shampoos, Cytopoint injections, Apoquel tablets, or allergen-specific immunotherapy (desensitisation). This is rarely a condition that goes away — it is managed.
Primary Seborrhoea
What it is: A hereditary condition causing the skin to overproduce sebum (skin oil), leading to a greasy, scaly coat and a distinctive rancid smell. The English Cocker Spaniel is one of the breeds most commonly affected.
Signs to watch for: Greasy, flaky skin and coat, a strong unpleasant smell even after bathing, yellow-brown waxy deposits in skin folds and around the ears, recurrent skin infections.
What to do: There is no cure — management involves regular medicated baths with antiseborrhoeic shampoos, dietary management, and treating any secondary infections. Your vet can recommend an appropriate bathing protocol and shampoo.
🧬 Hereditary conditions
Several serious conditions in Cocker Spaniels have a known genetic basis and can be identified through DNA testing of breeding dogs. When buying a puppy, always ask whether the parents have been health tested — reputable breeders will have documentation for the following.
Familial Nephropathy (FN)
What it is: A hereditary kidney disease specific to the English Cocker Spaniel, caused by a defect in the type IV collagen in the kidney's filtration membrane. Affected dogs develop progressive kidney failure, typically dying between 6 months and 2 years of age. It is devastating, incurable, and entirely preventable through responsible breeding.
Signs to watch for: Excessive thirst and urination, weight loss, vomiting, lethargy, poor coat condition in a young dog. These signs in a puppy or young adult Cocker should always prompt immediate veterinary investigation.
What to do: There is no treatment for FN. The condition is terminal. Management is palliative — kidney-support diet, hydration support, and quality of life management until the dog can no longer maintain a good quality of life.
Prevention: DNA testing eliminates this condition entirely from responsible breeding programmes. Both parents must be DNA tested. Insist on seeing certificates when buying a puppy.
CLAD (Canine Leucocyte Adhesion Deficiency)
What it is: A severe inherited immune deficiency causing affected puppies to be unable to fight infection. CLAD puppies typically die within the first few months of life from overwhelming infection. Like FN, it is caused by a recessive gene mutation and is entirely preventable through DNA testing.
Signs to watch for: Recurrent severe infections in a very young puppy, failure to thrive, wounds that do not heal, persistent fever. A puppy with CLAD will rarely survive to 6 months.
Prevention: DNA testing of both parents. Any reputable Cocker breeder will have CLAD test certificates available. Do not buy from a breeder who cannot provide them.
🦴 Orthopaedic conditions
Hip Dysplasia
What it is: Abnormal development of the hip joint, causing the ball and socket to fit together poorly. This causes progressive arthritis and pain. While more commonly associated with larger breeds, Cocker Spaniels have a higher incidence than many other spaniel types.
Signs to watch for: Reluctance to exercise, stiffness after rest, difficulty rising, bunny-hopping gait when running, visible muscle wasting in the hind legs. Signs typically appear from 1–2 years of age but worsen with age.
What to do: Mild cases are managed with weight control, physiotherapy, hydrotherapy, and anti-inflammatory medication. Severe cases may require surgical intervention — femoral head ostectomy (FHO) or total hip replacement (THR). The BVA/KC Hip Dysplasia Scheme scores breeding dogs' hips — look for parents with low combined hip scores.
⚖️ Weight management
Cocker Spaniels are enthusiastic eaters with a strong food drive, and obesity is one of the most common — and most preventable — health problems in the breed. Excess weight puts strain on joints, worsens any existing hip or elbow issues, and increases the risk of diabetes, heart disease, and shortened life expectancy.
A healthy adult Cocker Spaniel should have a clearly visible waist when viewed from above, and you should be able to feel (but not see) the ribs without pressing hard. If you cannot feel the ribs at all, the dog is overweight. Speak to your vet about a weight management plan — most practices offer free nurse weight clinics.
💡 Healthy weight tips for Cocker Spaniels
- Measure every meal — never free feed or estimate portions
- Count treats as part of the daily calorie allowance, not extras
- Use a slow feeder bowl to reduce eating speed and improve satiety
- Weigh your Cocker monthly and track it — gradual gain is easy to miss
- If neutered, reduce portions by 10–15% — neutering significantly reduces calorie needs
- High protein, lower carbohydrate food supports lean muscle and healthy weight — see our Cocker Spaniel food guide
🐾 Buying a healthy Cocker Spaniel puppy
The single most effective thing you can do for your Cocker Spaniel's long-term health is buy from a responsible breeder who health tests their dogs. Many of the most serious conditions on this page — FN, CLAD, PRA, hereditary cataracts — are entirely preventable when both parents have been DNA tested and screened.
When viewing a litter, ask to see the following documentation for both parents:
- DNA test certificates: PRA (CORD1), Familial Nephropathy (FN), CLAD — all should show "Clear" status
- BVA/KC eye test: Current certificate (within the last year) showing no hereditary eye conditions
- BVA/KC hip score: Both parents' combined score should ideally be below the breed mean (currently around 14)
- Kennel Club registration: Confirms the litter is recorded and the breeder is accountable
Reputable breeders will have all of this readily available and will actively want to discuss health testing with you. Walk away from any breeder who cannot provide test results, dismisses health testing as unnecessary, or pressures you to decide quickly.
✓ Key takeaways
Check your Cocker's ears weekly — it is the most important health habit for this breed. Take out lifetime pet insurance before your first vet visit. If buying a puppy, insist on DNA test certificates for PRA, FN, and CLAD from both parents. Maintain a healthy weight throughout your dog's life — it is one of the most significant factors in longevity and quality of life.
