Chronic Kidney Disease in Pugs: A Slow Decline That Can Be Managed

Increased thirst and more frequent urination are typically the earliest visible signs, though by the time these appear, kidney function has often already declined substantially. Reduced appetite and weight loss tend to follow as the disease progresses.

Bloodwork measuring creatinine and SDMA, combined with a urine test checking how well the kidneys concentrate urine, is the standard diagnostic approach, and results are used to assign a stage from 1 to 4.

No — kidney tissue that's been damaged generally doesn't regenerate, so management focuses on slowing progression and supporting remaining function rather than restoring the kidneys to full health.

Yes — prescription renal diets with reduced phosphorus and adjusted protein levels have been shown in veterinary research to meaningfully slow disease progression and are considered a core part of management from moderate stages onward.

This varies enormously by stage at diagnosis and how well the dog responds to management — some dogs live comfortably for a substantial stretch of time with early-stage disease and consistent management, while advanced-stage disease carries a more limited outlook.

SDMA is a blood marker that can detect kidney function decline earlier than traditional creatinine testing, sometimes flagging disease before as much kidney tissue has been lost, which allows management to start sooner.

It depends on stage — subcutaneous fluids given at home become more relevant for moderate to advanced disease to help maintain hydration and flush waste, and your vet will train you on the technique if it's recommended.
