Advancing age increases the likelihood of chronic kidney disease in dogs. As dogs get older, they experience gradual nephron loss and aging changes in the kidneys (such as scarring and fibrosis) that reduce filtration capacity. This makes CKD more common in older dogs, so age is a recognized risk factor.

Regular exercise generally supports overall health and kidney function, not increases CKD risk. Vaccination history does not have a direct link to CKD risk in dogs. A low-protein diet is not a risk factor for developing CKD; protein restriction is typically used as part of management after CKD is diagnosed, not as a cause of the disease.
