Neonatal mortality in dogs is high, ranging from approximately 5% to 35%, yet investigations into its causes and risk factors remain scarce. Postmortem examination is a crucial tool for identifying the underlying causes of neonatal death and improving disease diagnosis.However, the anatomical, physiological and histological differences between neonates and adults present unique challenges for necropsy procedures. Establishing a standardised neonatal necropsy protocol is essential for accurately determining the causes of death and associated diseases. This pilot study aimed to standardise a necropsy technique for canine neonates.During the examination, the spleen, heart, lungs, tongue, stomach, intestines, liver, pancreas, kidneys, bladder, brain and bones were collected from nine neonatal canines. The method involved monoblock organ removal, followed by separation on the basis of the standard organisation used in adult necropsies. Histological staining and analysis revealed structural
