A veterinary behaviorist wants to investigate whether diffusing synthetic dog appeasing pheromones (DAP) reduces high-arousal pacing behaviors in rescue dogs during feeding time compared to a control mist. The behaviorist plans to use an experimental design to test this.
Outline how the behaviorist could use random sampling to obtain a sample of 30 rescue dogs for this study from the population of 180 dogs currently housed at a local rehoming center.
