Circumstances, Descriptive Characteristics, and Pathologic Findings in Dogs Suspected of Starving.

The authors reviewed the case circumstances, population characteristics, gross, and histopathologic findings in 40 cases of emaciated dogs with a suspected diagnosis of starvation. The dogs’ estimated age ranged from 3 months to geriatric. Nineteen breeds were represented, including small-breed (n = 11), large-breed (n = 13), and pit bull–type (n = 16) dogs. The median body condition score was 1 out of 9 (Purina scale). Various diseases were identified as the cause of death in 7 dogs, while the cause of death in the other 33 dogs was starvation due to exogenous causes (SEC). Circumstances associated exclusively with SEC included being found in a vacated residence and death during temperature extremes or severe weather. Dogs with SEC did not differ significantly from diseased dogs in body condition score, sex, neuter status, or breed category (small, large, or pit bull type). Gross findings associated exclusively with SEC included severe hair matting and traumatic injuries. Diseased dogs had an empty stomach significantly more often than SEC dogs, which frequently had food and/or foreign material in the stomach. In 5 of the 7 cases where disease was the cause of death, disease involved the gastrointestinal tract. Gross and histopathologic changes commonly found in SEC and diseased dogs included the following: gross loss of muscle mass and absence of subcuticular fat; serous atrophy of omental, perirenal, epicardial, and bone marrow fat; atrophy of the liver, skin, thyroid gland, and testicle; gastric mucosal petechiae and ecchymoses; melena; and splenic hemosiderophages.
