The most common serious health issues of Standard Poodles listed in order of the number of reported cases in the Poodle Health Registry (20 August 2007) are Addison's disease, gastric dilatation volvulus, thyroid issues (hyperthyroid and hypothyroid), tracheal collapse, epilepsy, sebaceous adenitis, juvenile renal disease, hip dysplasia, and cancer. Standard Poodles are also susceptible to some health issues usually too minor to report to the health registry. The most common of these minor issues is probably ear infection. Ear infections are a problem in all poodle varieties because their nonshedding coat grows into the ear canal, where it traps wax and dirt. Ear problems can be minimized by proper ear care, including regular cleaning and plucking of hair within the ear canal. A veterinarian should be consulted if the dog shows signs of an ear infection.
Standard Poodles in UK, Denmark and USA/Canada surveys had a median lifespan of 11.5 to 12 years. In a UK survey, the most common causes of death were cancer (30%), old age (18%), GDV (6%), and cardiac disease (5%).
Addison's disease. Addison's disease is (as of 20 August 2007) the illness most commonly reported to the Poodle Health Registry. The number of reported cases is nearly twice as high as the next most common problem (GDV). Addison's disease is characterized by insufficient production of glucocorticoid and/or mineralocortoid in the adrenal cortex (near the kidneys). Addison's is often undiagnosed because early symptoms are vague and easily mistaken for other conditions. Standard Poodles with unexplained lethargy, frequent gastric disturbances, or an inability to tolerate stress should be tested for it. Addison's can cause fatal sodium/potassium imbalances, but if caught early and treated with lifelong medication, most dogs can live a relatively normal life.
Gastric dilatation volvulus. There is a high incidence of gastric dilatation volvulus (GDV) in this breed, which occurs when twisting of the stomach (volvulus or torsion) causes or is caused by excess gas. Symptoms include restlessness, inability to get comfortable, pacing, or retching without being able to bring up anything. The dog's abdomen may be visibly swollen, but bloat or torsion can occur without visible swelling. A dog with GDV requires immediate veterinary care. The dog's survival usually depends on whether the owner can get to a veterinarian in time. GDV risk is increased with faster eating and a raised feeding bowl.
