Summary

Venous blood lactate concentrations were measured on 109 ill dogs and 20 clinically normal dogs. Ill dogs were grouped into survivor and nonsurvivor groups, and categorized based on their primary problem. Ninety-five percent of ill dogs had lactate concentrations higher than clinically normal dogs and published normal values. Seventy-six percent of ill dogs with increased lactate concentrations survived to be discharged. Lactate concentrations were significantly higher in nonsurvivors than in survivors and clinically normal dogs. Lactate concentrations in dogs with major trauma and intoxications, and with cardiopulmonary, gastrointestinal, and neurologic problems were significantly higher than in clinically normal dogs and dogs with other problems.
