Health indicators for aging dogs and cats

Pet owners are advised to distinguish between normal aging and potential medical issues in dogs and cats. While aging increases the likelihood of disease, it should not be used as a default explanation for functional changes.

Heart disease is a significant concern, affecting approximately 10% of dogs and 15% of cats. Key warning signs include unusual fatigue, exercise intolerance, rapid or difficult breathing, coughing, weakness, fainting, reduced appetite, weight loss, and increased abdominal volume. For cats, breathing through an open mouth is considered an emergency.

Common cardiac conditions include degenerative valve disease, which is more frequent in small, older dogs, and dilated cardiomyopathy, often seen in larger breeds. In cats, hypertrophic cardiomyopathy, characterized by thickening of the heart walls, is a frequent issue.

Other age-related changes that require veterinary investigation include mobility difficulties, such as hesitating at stairs or difficulty jumping, which may indicate joint pain or muscle loss. Owners are encouraged to monitor persistent changes in behavior, appetite, and sleep patterns to facilitate individualized veterinary care.
