Osteoarthrosis in a coyote x dog hybrid from Nebraska

Osteoarthrosis is described in a wild, 14-year-old coyote (Canis latrans) x dog (C. familiaris) hybrid shot in southeastern Nebraska. There was ankylosis of five vertebrae, the head of the left femur was absent, and periarticular osteophytes occurred throughout the skeleton. The age is significant because wild coyotes seldom live beyond 6 years and coyote x dog hybrids are considered to be less fit for survival in the wild than coyotes.
