A number of mammals have been cloned, including cats and dogs. The purpose of this report was to study the bone fracture and bone fracture healing of three cloned dogs. The three cloned dogs, aged 3 months to 6 months, received separate surgeries. Clinical and radiological examination of each of the three cloned dogs revealed the fracture of a femur, a tibial tuberosity, and a humerus, respectively. Each dog had undergone surgical reduction and stabilization of their individual bone fracture with an intramedullary pin, a screw, and/or a wire. No abnormalities were observed during the follow-up period. The dogs showed normal callus formation and bone remodeling. Among the cases, the tibial tuberosity fracture was caused due to a breed-related fracture in a cloned greyhound. There was no evidence that these fractures were the result of cloning. Moreover, there were no complications including a delayed union, nonunion, malunion, or osteomyelitis during the healing process. All three cloned dogs showed normal bone fracture healing. To the author's knowledge, this is the first report about the bone healing of cloned dogs. Results show that long bone fractures in cloned dogs heal in the same manner as normal dogs.
