What are the early signs of kidney failure in a dog?

To understand what to watch for when it comes to your dog’s kidney health, start with the little shifts in their daily routine—those subtle changes that might slip by if you’re not paying close attention. These early signs often show up in how they drink, pee, eat, and act, and catching them fast can make a world of difference.

Your pup might start lapping up water like never before. You’ll find yourself refilling their bowl twice as often, and they’ll linger by it even after drinking. Along with that, their bathroom habits change—more trips outside, accidents in the house, or urine that looks diluted. It’s their body trying to flush out toxins, but it’s a red flag worth noting.

Mealtimes might feel different too. Suddenly, they’re turning up their nose at kibble they used to scarf down, or picking at treats they once begged for. You might notice their ribs showing a bit more, even if you haven’t changed their portions. Weight loss creeps in slowly, easy to dismiss as “just getting older,” but it’s often tied to how their kidneys are struggling.

Energy levels drop in quiet ways. The dog that bounded after squirrels now lies by the door, barely lifting their head when you jingle the leash. They might sleep more, or seem confused when you call them—little moments of disorientation that don’t fit their usual self. These aren’t just signs of aging; they’re clues their body isn’t processing nutrients right.

Bad breath that sticks around, even after a teeth brushing, is another hint. It might smell metallic or ammonia-like, a side effect of toxins building up. You might also see them licking their lips more, or vomiting occasionally—small, repeated issues that add up.

If you spot any of these, don’t wait. Schedule a vet visit promptly—they’ll run blood work and urine tests to check kidney function. Many areas require regular wellness exams, and catching issues early can align with local guidelines that prioritize preventive care for pets. Your vet can guide you through dietary changes or treatments that fit both your dog’s needs and community regulations.

Early detection turns a scary diagnosis into a manageable one. Those small, easy-to-miss signs? They’re your chance to step in, get help, and keep your pup comfortable for as long as possible. Paying attention isn’t just being a good pet parent—it’s giving them the best shot at more happy days.
