With prompt and aggressive veterinary treatment, the survival rate for dogs with leptospirosis is approximately 80%. While many dogs recover fully, the prognosis depends on the severity of kidney or liver damage, with some cases requiring intensive care like dialysis to survive. Survival drops to 40-50% if severe lung involvement occurs.

How long can dogs live with leptospirosis?
