Abstract
Dogs and cats represent only a small proportion of animals used for scientific purposes, but anesthetic and analgesic practices in these species are relatively advanced and more often evidence-based, due to their popularity as companion animals. This chapter discusses the importance of individualized anesthetic planning; pharmacological techniques for sedation and anesthesia including partial intravenous anesthesia, total intravenous anesthesia, and loco-regional anesthesia; and the detection and management of common anesthetic complications. Finally, approaches to the assessment and management of acute and chronic pain in these species are discussed.
