Cocker Spaniels are charming, expressive, and famously affectionate — but their long ears, soulful eyes, and silky coats come with a known set of breed-specific health risks. If you share your life with a Cocker, understanding common cocker spaniel health problems helps you spot trouble early.
Here are the issues most owners need to know about.
Ear Infections (Chronic Otitis)
This is the single most common Cocker Spaniel health issue. The breed's heavy, pendulous ears reduce airflow in the ear canal, creating a warm, humid environment that bacteria and yeast love. Research from the Royal Veterinary College found English Cocker Spaniels are roughly 15 times more likely to be diagnosed with ear discharge than other breeds (AAHA Canine Life Stage Guidelines, 2019).
Signs to watch for
- Head shaking or tilting
- Scratching at the ears
- Odor coming from the ears
- Brown, yellow, or waxy discharge
- Redness or swelling inside the ear flap
Prevention tip: weekly ear checks and a vet-recommended ear cleaner are essential. Trimming the fur inside the ear (your vet or groomer can show you) helps airflow.
Eye Problems
Cockers are prone to several eye conditions, including:
- Cherry eye — prolapse of the third eyelid gland, often in young dogs
- Cataracts — clouding of the lens, sometimes related to diabetes
- Glaucoma — increased eye pressure, a painful emergency
- Progressive retinal atrophy (PRA) — gradual vision loss that often starts as night blindness
- Dry eye (KCS) — reduced tear production, causing chronic discharge and ulcers
Annual eye exams from age 1 onward are recommended.
Skin Conditions
The breed's predisposition to atopy (environmental allergies), seborrhea (oily, flaky skin), and hypothyroidism can all show up as skin issues. Owners may notice itching, recurrent skin infections, hot spots, or a greasy coat with a distinct smell.
Regular grooming, parasite control, and an allergy plan from your vet make a big difference.
Heart Disease
Cockers are at higher risk of dilated cardiomyopathy (DCM) and mitral valve disease as they age. These can develop quietly until coughing, exercise intolerance, or fast breathing appear.
Yearly heart auscultations and senior wellness exams help catch heart disease early when treatment is most effective.
Hip Dysplasia and Joint Issues
Hip dysplasia and patellar luxation occur in Cockers. Signs include:
- Stiffness after rest
- Reluctance to jump or climb stairs
- A bunny-hopping gait
- Limping that comes and goes
Reputable breeders screen for hip and knee issues. Keeping your Cocker at a lean body weight is one of the best things you can do for joint health.
Hypothyroidism
A common endocrine disorder in the breed. Watch for weight gain, lethargy, hair thinning, cold intolerance, and recurring skin infections. A simple blood test diagnoses it, and daily medication usually controls it well.
Autoimmune and Blood Disorders
Cockers have a higher rate of autoimmune hemolytic anemia (AIHA) and immune-mediated thrombocytopenia (ITP). Signs include pale gums, weakness, dark urine, and bruising. These are emergencies — go to the vet right away if you notice them.
When to Worry
Call your vet promptly if you notice any of these warning signs:
- Persistent head shaking or ear pain
- Cloudy eyes, redness, or vision changes
- Sudden weakness, pale gums, or rapid breathing
- Coughing, especially at night or after exercise
- Unexplained weight changes, lethargy, or appetite shifts

What To Do at Home
Weekly ear cleaning is non-negotiable for this breed. Use a vet-approved cleaner and dry gently.
Annual wellness exams plus more frequent senior checkups (every 6 months after age 8) catch issues early.
Quality nutrition for a lean body weight protects joints, heart, and skin.
Grooming routine — brushing 2–3 times a week prevents matting and skin issues.
Know your dog's "normal" — energy level, eating habits, and coat condition. Changes are often the first hint of trouble.
