Can you survive tetrodotoxin?

Death may occur as early as 20 minutes, or as late as 24 hours, after exposure; but it usually occurs within the first 4 to 8 hours. Patient/victims who live through the acute intoxication in the first 24 hours usually recover without residual deficits.

What happens if a dog eats a puffer fish?
