Poodle Health Issues: Screening

The Poodle, in its Standard, Miniature and Toy varieties, carries a distinct set of heritable conditions that prospective owners, breeders and veterinarians need to understand. This article covers the most common and clinically significant health problems in Poodles, the genetic tests available, screening recommendations from major health organisations, what to ask a breeder and how to manage affected dogs.

For a full overview of the breed's history, temperament and care requirements, see Poodle.

Why Poodle Health Matters

The three Poodle varieties share most of the same heritable conditions but differ in prevalence for some disorders. Standard Poodles, being the largest, carry the highest risk for certain orthopaedic and cardiac diseases. Miniature and Toy Poodles share a slightly different risk profile with elevated rates of patellar luxation and Progressive Retinal Atrophy.

Progressive Retinal Atrophy

Progressive Retinal Atrophy (PRA) encompasses a group of inherited degenerative eye diseases in which the photoreceptor cells of the retina gradually degenerate, leading to progressive vision loss and eventual blindness. In Poodles, the dominant form is prcd-PRA (progressive rod-cone degeneration), caused by a recessive mutation in the PRCD gene.

A dog must inherit two copies of the mutant allele (homozygous recessive) to be clinically affected. Dogs with one copy (carriers) are not affected but can pass the allele to offspring. Because the condition is recessive, two carrier dogs bred together have a 25% chance of producing an affected puppy.

The prcd-PRA mutation has been identified across multiple breeds, and Poodles are one of the breeds with the highest studied prevalence. DNA testing at commercial laboratories (Embark, Wisdom Panel, Optigen and the OFA CHIC program) can definitively classify dogs as clear, carrier, or at risk/affected.

Responsible breeding practice is to test all breeding candidates and avoid pairing two carriers. A carrier bred to a clear dog produces 50% carriers and 50% clears, but no affected dogs, this allows carriers of otherwise excellent breed quality to remain in the gene pool without producing affected offspring.

Clinical signs of prcd-PRA appear in adult dogs. Initial signs include night blindness (reduced vision in dim light), followed by day blindness as cone photoreceptors also degenerate. Owners often first notice the dog becoming hesitant in unfamiliar low-light environments. The condition progresses over years to total blindness. There is no treatment, management focuses on environmental stability and enrichment.

Sebaceous Adenitis

Sebaceous adenitis (SA) is an inflammatory skin disease in which the immune system attacks and destroys the sebaceous glands (oil glands) in the skin. It is one of the most distinctive and well-documented breed-specific conditions in Standard Poodles.

The OFA sebaceous adenitis registry for Poodles shows that among dogs submitted for evaluation, a substantial proportion have subclinical or clinical disease, though submitted dogs are not representative because affected dogs are more likely to be submitted. Prevalence in the Standard Poodle population is estimated at about 2.7%.

Clinical signs vary with disease severity. Mild cases present as scaling, dandruff-like flaking along the dorsal midline (top of the back, neck and head), often with loss of the characteristic curly coat texture, affected areas develop a dull, matted, or wavy appearance. Moderate-to-severe cases show alopecia (hair loss), silver-white scaling adherent to hair shafts, musty odour and secondary bacterial infections in the compromised skin barrier. The face and ears are frequently affected.

Diagnosis is confirmed by skin biopsy showing characteristic destruction of sebaceous glands with a granulomatous or lymphocytic infiltrate. The OFA maintains a voluntary registry where biopsy results can be recorded.

Treatment is not curative. Management involves: oil-based treatments (cyclosporine-rich sprays, baby oil soaks, or evening primrose oil supplementation) to compensate for reduced sebum production, antiseborrhoeic shampoos, cyclosporine (an immunosuppressant) which reduces inflammation and can stabilise the condition, and regular monitoring for secondary infections. Most affected dogs live normal lifespans with attentive management.

Addison's Disease

Addison's disease (hypoadrenocorticism) results from the destruction of the adrenal cortex, causing deficiency of both glucocorticoid (cortisol) and mineralocorticoid (aldosterone) hormones. Standard Poodles have one of the highest breed-specific prevalences of Addison's disease of any dog breed.

The condition is thought to be immune-mediated in most cases, meaning the immune system attacks the adrenal cortex. A genetic predisposition has long been recognised in Poodles, and genome-wide association studies have identified candidate loci, though a reliable single-gene test does not yet exist.

Addison's disease is notoriously difficult to diagnose because symptoms are vague, episodic and mimic many other conditions, earning the nickname "the great pretender" in veterinary medicine. Signs include: episodic lethargy or weakness, vomiting, diarrhoea, weight loss, poor appetite, muscle wasting and shaking.

Many dogs are mildly affected for months to years before acute adrenal crisis (Addisonian crisis), which presents as collapse, severe weakness, bradycardia (slow heart rate), hypothermia and shock, representing a life-threatening emergency.

Diagnosis is by the ACTH stimulation test, which measures the adrenal gland's cortisol response to stimulation. Treatment is lifelong hormone replacement with a desoxycorticosterone pivalate (DOCP) injection (every 25-30 days) for mineralocorticoids, and oral prednisolone (or equivalent) for glucocorticoids. Dogs on lifelong treatment live normal healthy lives. Additional glucocorticoid supplementation is required during physical stress (surgery, illness, injury) to prevent crisis.

Hip Dysplasia

Hip dysplasia (HD) is an abnormal development of the hip joint in which the femoral head does not fit correctly in the acetabulum, leading to joint laxity, cartilage degradation and osteoarthritis. Hip dysplasia is a recognised concern in Standard Poodles.

Risk factors include genetics, rapid growth, excess weight during puppyhood and exercise type during skeletal development. Breeding dogs should be OFA-certified (rated fair, good, or excellent) or have favourable PennHIP results. Both parents must be evaluated before breeding.

Clinical signs include rear limb lameness, reluctance to climb stairs or jump, a bunny-hopping gait at trot or canter and reduced activity. Diagnosis is by radiograph. Mild cases are managed with weight control, appropriate exercise (swimming is ideal), joint supplements (omega-3 fatty acids, glucosamine/chondroitin), and NSAIDs as needed.

Severe cases in young dogs can benefit from surgical intervention: triple pelvic osteotomy (TPO) in puppies or total hip replacement in skeletally mature dogs.

Gastric Dilatation-Volvulus

Gastric dilatation-volvulus (GDV), commonly called bloat, is one of the most serious acute emergencies in veterinary medicine and one for which Standard Poodles have elevated lifetime risk. GDV occurs when the stomach fills with gas and then rotates on its long axis (volvulus), trapping gas and cutting off blood supply to the stomach and spleen. Without emergency surgery, GDV is fatal within hours.

Risk factors identified in the literature include: deep and narrow chest conformation (the Standard Poodle's conformation increases risk), large body size, eating speed (rapid consumption of large meals), single large meals versus multiple smaller meals, and genetic predisposition.

Prophylactic gastropexy (surgically tacking the stomach to the abdominal wall) is strongly recommended for Standard Poodles, particularly when spaying or neutering, as it essentially eliminates volvulus risk while dilatation can still occur. Owners should be familiar with the early signs of GDV: unproductive retching, a distended or drum-tight abdomen, restlessness, drooling and pale gums. This is always a veterinary emergency.

Neonatal Encephalopathy with Seizures

Neonatal Encephalopathy with Seizures (NEWS) is a recessively inherited neurological condition unique to Standard Poodles. Affected puppies appear normal at birth but within the first weeks of life develop progressive neurological signs including severe ataxia, abnormal gait and tonic-clonic seizures. Affected puppies do not survive or are humanely euthanised due to severity of signs.

A DNA test is available through multiple commercial laboratories. As with prcd-PRA, two carriers bred together produce 25% affected offspring. Because affected puppies die before weaning, breeders may occasionally produce affected litters without knowing they were breeding two carriers. All Standard Poodle breeding candidates should be tested.

Screening Recommendations by Variety

Variety	Recommended Screening	Issuing Body
Standard Poodle	Hip radiograph (OFA/PennHIP), eye examination (CAER annual), sebaceous adenitis (OFA skin biopsy), thyroid panel, prcd-PRA DNA, NEWS DNA, vWD DNA	OFA CHIC Program
Miniature Poodle	Eye examination (CAER annual), prcd-PRA DNA, patellar evaluation (OFA), hip radiograph	OFA CHIC Program
Toy Poodle	Eye examination (CAER annual), prcd-PRA DNA, patellar evaluation (OFA)	OFA CHIC Program

The OFA Canine Health Information Center (CHIC) issues a CHIC number to dogs that have completed all breed-specific required health tests and whose results are publicly available, regardless of outcome. CHIC certification means the tests have been done, it does not mean the dog passed all tests.

What to Ask a Poodle Breeder

Before purchasing a Poodle puppy, prospective owners should request documentation for the following:

• OFA hip evaluation (fair, good, or excellent) or PennHIP results for both parents, for Standard and Miniature
• OFA/CAER ophthalmologist eye examination performed within the past 12 months for both parents
• prcd-PRA DNA test result showing clear or carrier status for both parents
• NEWS DNA test result for Standard Poodle parents
• Thyroid panel results for Standard Poodle parents
• Any sebaceous adenitis biopsy results or OFA SA registry entries for Standard Poodle parents
• CHIC number for both parents (verifiable at ofa.org)
• Addison's disease history in the line (no genetic test exists, but breeders should disclose if the disease has appeared in close relatives)

A reputable breeder should be able to provide all test documentation without hesitation.

Management and Ongoing Care

For Standard Poodles:

• Perform prophylactic gastropexy at the time of spay or neuter surgery
• Feed multiple small meals rather than one large daily meal, use slow-feeder bowls
• Keep an eye out for early signs of Addison's disease and notify every veterinarian that this breed has an elevated risk.
• Schedule annual CAER ophthalmology examinations through middle age
• Maintain lean body weight to reduce hip osteoarthritis progression

For all Poodles:

• Annual thyroid checks from middle age onward
• Ears require routine inspection and cleaning, the Poodle's pendulous, hair-lined ear canal predisposes to moisture accumulation and chronic otitis externa
• Dental care: Toy and Miniature Poodles have higher rates of dental crowding and periodontal disease given teeth-to-jaw ratio
• Regular grooming every 6-8 weeks is health care, not just cosmetic, matted coats trap moisture and cause skin infection, and can conceal sebaceous adenitis lesions
