The reliability of any NOEL derived from this study should be considered questionable, owing to the presence of infection in all groups. Dogs of undetermined breed or source were given xylazine orally in gelatin capsules for 14-16 weeks at dose levels of 25, 50 or 100 mg/kg bw per day, 5 days/week. The low-dose group consisted of one male and one female, the mid-dose group of two males and the high-dose group of two males and two females.
