Hereditary Conditions in Golden Retrievers

Like all dog breeds, Golden Retrievers can inherit certain health conditions. Breeders who are members of the Golden Retriever Club of Queensland Inc. are encouraged to follow the Club’s health guidelines. These include having breeding dogs checked by veterinarians using recognised tests such as X-rays and specialist eye examinations before they are bred.

The two most common inherited conditions seen in Golden Retrievers are Hip Dysplasia and Eye Disorders.

Hip Dysplasia

Is a condition where the hip joint does not develop properly. The hip joint works like a ball fitting into a socket. In dogs with Hip Dysplasia, this joint is loose or misshapen, which can cause pain and reduced movement over time.

The condition can be mild or severe. Some dogs may show few outward signs when they are young, but arthritis often develops as they get older.

The only way to accurately diagnose Hip Dysplasia is with an X-ray. Responsible breeders arrange hip X-rays for their dogs before breeding and send them to an official scoring system. Each hip is given a score, and lower scores mean healthier hips.

Many dogs with Hip Dysplasia still live happy and active lives, especially with modern veterinary care and proper management. Only very severe cases may not be treatable.

Puppy owners can help protect growing joints by:

• Keeping puppies at a healthy weight
• Avoiding too much exercise while they are growing
• Not allowing puppies under 12 months of age to jump on and off furniture or high surfaces

When buying a puppy, ask the breeder to show you the hip scores of the puppy’s parents and explain what they mean. While hip scoring helps reduce the risk of Hip Dysplasia, it cannot guarantee that a puppy will never develop the condition.

Responsible breeders follow the health guidelines set by canine controlling bodies and the Golden Retriever Club of Queensland Inc. to help improve the long-term health of the breed.

Elbow Dysplasia

Is a condition where a puppy’s elbow joint does not develop properly. It includes several different problems that affect how the bones and cartilage in the joint grow and fit together. These problems can damage the joint and lead to arthritis as the dog gets older.

The three most common types of Elbow Dysplasia are:
• Osteochondritis Dissecans (OCD)
• Fragmented Coronoid Process (FCP)
• Ununited Anconeal Process (UAP)

These problems develop while a puppy is growing and cause uneven wear inside the joint. Because the elbow is a very active joint with a complex shape, it is especially prone to this condition.

Signs of Elbow Dysplasia usually appear between 4 and 6 months of age and may come and go. Dogs may:

• Look stiff when getting up from rest
• Limp slightly, especially after exercise
• Be reluctant to run or play for long
• Male dogs are more commonly affected.

Treatment depends on how serious the condition is and may include surgery, medication, or both.

Elbow Scoring

Breeding dogs can have their elbows X-rayed and scored, usually at the same time as hip X-rays. Each elbow is given a grade from 0 to 3:
Grade 0 – normal elbow with no signs of disease
Grade 3 – severe arthritis

Lower scores indicate healthier elbows.

Elbow Dysplasia is influenced by genetics as well as growth and lifestyle factors. It is not caused by just one gene, but by a combination of many genes. The risk can be reduced by:

• Avoiding rapid growth caused by overfeeding
• Keeping puppies at a healthy weight
• Not over-exercising young puppies

These steps help protect growing joints.

Eye Diseases in Golden Retrievers

Entropion
Entropion is an inherited condition where the eyelid rolls inward, causing the eyelashes to rub on the surface of the eye. This usually affects the lower eyelid and is most common in dogs under one year of age. It causes irritation and can lead to ulcers on the eye. Surgery is required to correct it.

Distichiasis
This condition involves extra eyelashes growing from the edge of the eyelid and touching the eye. Some dogs are not bothered, but if irritation occurs, surgery may be needed.

Persistent Pupillary Membranes (PPM)
Many Golden Retrievers have mild PPMs, which appear as small strands of tissue in the eye. Most do not cause any vision problems.

Imperforate Tear Duct (Tear Punctum)
In some dogs, the tear duct opening does not form properly, causing watery eyes from a young age. Surgery can be performed to create a new tear duct opening.

Cataracts
A cataract is a clouding of the lens of the eye. Some cataracts are inherited and may lead to blindness if they worsen. Surgery is possible in some cases.
A common type in Golden Retrievers is the “star cataract,” which usually appears between 6 and 18 months of age. It rarely affects vision.

Progressive Retinal Atrophy (PRA)
PRA is an inherited disease where the light-sensitive layer at the back of the eye slowly degenerates. Dogs first lose night vision, then daytime vision, and may eventually become blind.

Heart Disease in Golden Retrievers

Golden Retrievers can inherit certain heart conditions. The most common inherited heart disease in the breed is Subaortic Stenosis (SAS), which can be serious and may be fatal at a young age.

Breeding dogs should be checked for heart disease before being used for breeding. Heart clearances should be issued after 12 months of age, as a puppy heart check does not confirm long-term suitability for breeding. (Heart testing is not compulsory for litter registration.)

Subaortic Stenosis (SAS)

SAS occurs when abnormal tissue near the aortic valve restricts blood flow from the heart. In severe cases, this can lead to heart failure or abnormal heart rhythms.

Signs may include:

  • Tiring easily during exercise
  • Weakness in the back legs
  • Fainting
  • Coughing or difficulty breathing
  • Sudden death in severe cases

A heart murmur and irregular heartbeat can be warning signs. Diagnosis may involve X-rays, ECGs, and heart ultrasound (echocardiogram).

Treatment depends on severity and may include medication, surgery, or balloon procedures. Mildly affected dogs can live a good quality of life, but more severe cases have a poorer outlook.

Ichthyosis (Skin Disease)

Ichthyosis is an inherited skin condition in Golden Retrievers that causes heavy dandruff and dry, scaly skin. Symptoms usually appear between 1 and 18 months of age. Affected dogs may have:

  • Large amounts of dandruff, especially on the back and belly
  • Dry, rough or thickened skin
  • Darkened (pigmented) skin
  • A “dirty” or scaly appearance

The condition can sometimes be mistaken for parasites or poor hygiene. Special shampoos and good skin care can help prevent infections, but there is no cure.

Many Golden Retrievers carry the gene for Ichthyosis without showing any signs. A dog that is a carrier will not be affected but can pass the gene on to its puppies. If both parents are carriers, some puppies may be born with the disease.

A reliable DNA test (ICT-A) is available and can identify whether a dog is:

  • Clear
  • Carrier
  • Affected

The test is simple and involves a cheek swab taken by a veterinarian. Results are usually available within a few days.

Responsible breeders use DNA testing to plan matings carefully and avoid producing affected puppies. Testing helps reduce the spread of Ichthyosis in the breed and protects future generations.
