The adult Lhasa Apso, typically reaching full maturity between eighteen months and two years, enters a period of relative stability that represents the prime of its life. This stage, which spans from roughly two years to around eight or nine years of age, is when the Lhasa Apso is at its physical peak. The breed's robust constitution and longevity mean that with proper care, the adult years can be an extended period of vitality and good health.
Annual wellness examinations form the backbone of preventive health care during the adult years. These visits allow your veterinarian to assess your dog's overall condition, update vaccinations as needed, perform routine blood work, and screen for early signs of conditions that are common in the breed. The Lhasa Apso is predisposed to certain health concerns including patellar luxation, progressive retinal atrophy, and renal dysplasia, making regular screening particularly valuable.
Maintaining a healthy body weight is one of the single most effective things an owner can do to support long-term health. The Lhasa Apso's small frame means that even a pound or two of excess weight places disproportionate stress on joints, organs, and the cardiovascular system. Regular body condition assessments — checking that you can feel the ribs without pressing hard and that there is a visible waist when viewed from above — help keep weight on track between veterinary visits.
Parasite prevention should continue year-round for the adult Lhasa Apso. Fleas, ticks, and heartworm remain threats regardless of the dog's age, and consistent use of veterinarian-recommended preventive products provides reliable protection. Intestinal parasite screening through annual fecal examinations ensures that any infections are caught and treated promptly.
