The fourth ventricle of the brain's chemoreceptor trigger zone is directly stimulated by opioids, which sets off the vomiting reflex.

Despite the fact that both animals will salivate and display symptoms of nausea, dogs are more prone to this than cats. If their stomach is not completely empty after at least 6 hours of fasting before anesthesia, dogs are more prone to vomit.
Vomiting is more frequent in dogs, which may partly explain why it occurs more frequently in mobile patients of humans as opposed to those who are lying down.
Following vomiting, dogs frequently defecate as well. When given as a premedicant, morphine is more likely than other frequently used opioids to cause nausea, vomiting, and salivation in healthy animals.
Therefore, opioids are involved in triggering the chemoreceptor trigger zone.
