Kaplan–Meier curves comparing normal and affected dogs for cold (A) and heat (B) latencies (s) and mechanical (C) thresholds (kg). Data from every trial of every dog were included. Responses were censored when there was no response by 60 (cold) or 30 (heat) seconds. Affected and normal dogs are significantly different for all 3 modalities (P < .0001).
