Known Health Concerns in English Cocker Spaniels
‘When a test is developed for any disease, there should be no reason to ever produce a puppy adversely affected by that disease.’ Gary F. Mason (1999)
Unfortunately, many dogs are prone to a range of hereditary diseases and the cocker spaniel is no exception. A reputable breeder should be breeding from dogs that have been tested so that all genetic health conditions are known. Therefore it's a sensible precaution when looking for a puppy to choose a breeder who makes every effort to DNA test their breeding stock. If you have any concerns check with your vets before making a final decision.
DNA testing (99.9% accurate) is now readily available and economical it is part of a good reputable breeders program to test all breeding stock to ensure that known disease is not passed on to the next generation. You owe it to your self to ensure that your new puppy or its parents have been tested for commonly inheredited health conditions known in cocker spaniels.
Reputable breeders are doing all they can to eliminate these diseases from future generations, But its important that you understand what to ask about and the implications of purchasing a puppy with these inherited diseases. There are 2 potential health conditions which you should check on when talking to a cocker spaniel breeder about their breeding program and potential puppies that the parents can be DNA tested for prior to being mated - PRA & FN. A 3rd condition comonly seen in NZ, which is not diagnosed by DNA is Entropion, this can only be diagnosesed by a Canine Ophthalmologist.
I regularly get enquiries askig for advise about purchasing a cocker spaniel puppy. Its great that people are using the internet to make informed decissions before taking the plunge, so at the bottome of this page I have included copies of DNA certifiates for PRA-prcd & FN and an Ophthlmologist Certifcate so you'll know what to expect when you ask to see them from any reputable breeder.

PRA - Progressive Retinal Atrophy
Don't just assume your cocker has gone blind from old age at 5 or 6years old. PRA is a disease in which the retina slowly deteriorates, producing night blindness in young dogs. As PRA progresses, dogs become totally blind.
The best way to minimize the chance of buying a puppy that will later be affected by one of these inherited eye conditions is by asking for copies of the DNA results of the parents... Read more >
AHRN Autosomal Hereditary Recessive Nephropathy or commonly called FN - Familial Nephropathy
This is an inherited renal disease that causes juvenile-onset renal failure has been recognized in Cocker Spaniels worldwide for more than 50 years. FN is progressive and ultimately fatal.
Dogs with FN develop chronic renal failure, usually while they are between 6 months and 2 years of age.
The signs associated with chronic renal failure caused by FN often include excessive water consumption, excessive urine volume, reduced growth rate or weight loss, poor quality hair coat, reduced appetite, and vomiting. Such signs can develop gradually and can be overlooked until the degree of renal failure is severe, by which time symptoms may include thin body condition, dehydration, pallor of mucous membranes, uremic breath odor, and oral ulcerations. However, especially at earlier stages of the disease, physical exam findings may be normal, this is one reason why DNA testing is important in breeding stock.
FN is progressive and ultimately fatal; however, the rate of disease progression in some dogs is more rapid than in others. Certain treatments such as feeding a diet formulated for dogs with renal failure and medication may slow the rate of renal disease progression somewhat. The rate of renal disease progression usually is fairly rapid during the late stages of the disorder.
DNA Testing is available for this disease, and dogs being breed from should be tested to ensure the disease is not passed onto future generations.
From an article by George E. Lees, DVM, MS, DACVIM who has been carrying out genetic studies on FN in Cocker Spaniels since 1997

Others Conditions to be aware of
While the following are not necessarily inherited they can reduce the quality of life with your cocker spaniel and increase the costs of owing your faithful companion. So it's a good idea to check and see whether others in your puppies family tree suffer from any of these conditions.
Entropion
The inward rolling of the eyelid, most commonly the lower lid. This irritates the surface of the eye (the cornea) and may ultimately cause visual impairment. Generally both eyes are affected.
It is a common hereditary disorder and in some instances the selection of exaggerated facial features with prominent eyes and/or heavy facial folds, has created or worsened this problem.
The problem is usually evident before the dog is a year of age and can occasionally be seen in puppies as young as 6 weeks of age. The dog may be sensitive to light and rub at its eyes. Chronic irritation caused by the turned in eyelid may cause corneal ulceration and scarring which is painful and, if not corrected, can impair vision.
Entropion may be corrected surgically, but this procedure should be delayed until the dog is an adult, since the involved facial structures are still growing and changing.
Breeders should avoid using cockers affected with this condition in their breeding programmes. And those that have had they dogs surgical corrected and contiue to breed from them are causing pet owners no end of heart break and unwarranted exspense and their pets needless discomfort.
*** NB this is a condition that I have seen in a number of cocker spaniels in NZ. In fact the very frst cocker we brought as a show dog suffered with this condidtion amongst others. Even though I thought I asked the right questions when enquirying about him. He has since been nuetered and lives in a pet home. I now know that you need to see the parents and the puppies health certficates, and these are not available from a standard vet. If you have any doubts about your cocker, please take it to your vet for advice on relieving the discomfort your cocker is suffering from.
Ectropion
Basically its the opposite of the above condition. A herediary defect of conformation in which there is a sagging or rolling out of the eyelids, resulting in abnormal exposure of the eye which also lead to irritation and infection.
Breeders are advised to avoid using cockers affected with this condition in their breeding programmes
Cataracts
Cataracts are defined as any opacity (imperviousness to rays of light) in the lens of the eye. Some cataracts remain small and do not result in any clinical impairment of vision. In other cases dogs affected by cataracts experience cloudiness of vision and, ultimately, blindness. Cataracts, which can affect one or both eyes, can sometimes be corrected by surgery.
Ear Infections
Cockers can be prone to ear infections and seborrhea (greasy, flaky skin). Their long, silky coats and ears require more than average attention if they are to remain beautiful throughout the cocker's life, which can reasonably be expected to last 12 to 15 years. This common condition can be help immenseley by keeping the inner hair on the ears trimmed back to allow for as much air flow as possible. A quick test to see if your dog needs his ears cleaned - is by smell! If they smell a bit yukky - clean them using the appropriate ear powder available from vets and pet stores.
Hip dysplasia
Hip dysplasia is a genetic degenerative joint disease which leads to abnormal formation of the hip socket and is one of the most common hereditary problems affecting dogs. It causes terrible pain and suffering on the part of the dog, leading to gradual debilitation until the everyday activities become too painful and the dog is not even able to walk. It is not a disease of old dogs either - dogs as young as 6 months have been diagnosed with hip dysplasia, although in most cases, symptoms will not start developing until the puppy has matured.
The best way to prevent hip dysplasia is to buy a puppy from parents whose hips have been hip scored. Hip Scoring is a screening test which assesses a dog's hips through radiographs and then scores them, from 0 (best) to 106 (worst). You can not tell just by looking - a dog may be active and mobile for several years before developing hip dysplasia.
Heart Conditions
Inherited heart defects are common in many breeds, therefore, it is vital that breeders with a dog known to have a heart condition has the dog tested to ensure its is not a hereditary condition. However heart conditions often don't show up until later in life, therefore a dog that has been tested as normal and healthy (and is therefore used for breeding) can develop heart disease when it gets older, by which time it is too late as it has already passed its genes onto its puppies. Therefore, even the most responsible breeders can sometimes find it hard to screen for these conditions.
