How Long Until a Puppy Dies After Eating Rat Poison?

After a puppy eats rat poison, with a large dose it may die in about half an hour, or at most within 24 hours; the exact time depends on the type, concentration, and amount ingested. If it ate a strong poison, obvious neurological or other abnormal symptoms usually appear within half an hour, followed by rapid death.

If the poison is weak or the amount ingested is tiny, timely treatment may prevent death.
