#Dogs 🐕 were preferred over #monkeys 🐒 because they were more trainable than primates and tolerated longer periods of inactivity better, tending to panic and react unpredictably less under pressure. In contrast, the monkeys in the American test series had to be sedated with medication, which influenced the research results.
