Excessive Water Drinking – Heat or Renal Warning Sign?

TernaryWeevil8816
Report

An 8-year-old Labrador showed consistent elevated water intake in cool autumn with no extra activity or diet changes, waking its owner multiple times nightly to drink. The owner initially blamed dry air; follow-up testing revealed slightly elevated SDMA, indicating early renal compensation impairment.

    Hello, When a dog starts drinking much more than usual, a check-up with the vet is essential, as this "polydipsia" can be the first sign of kidney disease, as well as other conditions such as diabetes mellitus, Cushing's syndrome (hyperadrenocorticism), pyometra in an unspayed female, or certain liver diseases. Furthermore, an elevated SDMA alone is not enough to diagnose chronic kidney disease. This result must be interpreted alongside a physical exam, a urinalysis (specifically looking at urine specific gravity and checking for proteinuria), creatinine, urea and, if necessary, a kidney ultrasound to confirm the source of the problem and assess its severity. Early intervention often helps to slow the progression of the disease once kidney damage has been confirmed. Best wishes, Inès

    It's really important to pay attention to things that might seem minor, like drinking or urinating more often, or having an unexpected accident in the house when it never usually happens... It could be a sign of early-stage kidney failure that might still be manageable at that point... Don't hesitate to speak to your vet about it.

    Hi there

    It's the height of summer — it's August, not the middle of autumn or the start of October. Despite time zones, the date is still the same 😀

    That said, I think you need to be vigilant and observe **when a change in behaviour happens suddenly, without explanation.**

    Monitoring means:

    • noting down exactly how much they are eating and drinking.

    • checking their temperature and weight

    • checking their sleep and general behaviour (appetite, for instance...)

    It could be due to a change in their diet, like treats that turn out to be quite salty.
