How is dog apomorphine administered?

Apomorphine is generally the emetic of choice in dogs because of its rapid onset and the ability to reverse its action. Apomorphine is given at a dose of 0.02 to 0.04 mg/kg intravenous (IV) or intramuscular (IM). It can also be administered by placing it directly behind the eyelid in the subconjunctival sac.

Is apomorphine safe for dogs?

Apomorphine. Typically not recommended as it is not likely to be effective, due to species differences between dogs and cats. The dog's chemoreceptor trigger zone (CRTZ) is controlled largely by dopamine receptors, so apomorphine typically induces emesis.
