Although usually used for diagnostic purposes to rule out potential life-threatening conditions (eg, bacterial meningitis or subarachnoid hemorrhage), it is also sometimes used for therapeutic purposes . The authors found that the Jack Russell terrier was responsible for approximately 10% of bites, and 8/10 of the most popular breeds were the most common biters (including the highly polymorphic group of mixed breed/mongrel).46 Furthermore, the necessary objective methods of determining the breed of the involved dog (pedigree analysis and DNA testing) are potentially time consuming, expensive, and mostly complicated efforts.14 Inconsistencies are not unusual.

Odontological analysis of bite marks may provide conclusive evidence in identifying a particular animal.3,31 While in the presence of multiple animal bites, it is difficult to apply a bite mark protocol that would record every wound individually, take impressions, and remove all of the affected tissue,1 the guidelines provided by the American Board of Forensic Odontology (http://www.abfo.org) for human bite mark analysis may be useful in the implementation of the photographic protocol and in the improvement of the quality of the expertise, resulting in more strong dog identification.16 Souviron recommends taking black-and-white, color, or alternate light photographs and video documentation.

An appropriate forensic approach must include detailed assessment of the scene, the victim, and the animals involved. Both experts clarified that although the evidence in this particular case was sufficiently categorical to establish the animal species that produced the fatal attack, the poorly processed scene and the lack of complete information of the autopsy were completely irregular and could lead to wrong conclusions (the preliminary hypothesis considered that the attack was produced by a cougar or a big dog).17. 2. J Forensic Sci. Forensic Sci Int. Also a forensic biologist can provide additional data on sources of attacks or scavenging that can be used to evaluate such incidents.1,6,8,13 In a case reported by Fonseca and Palacios, a forensic odontologist and a carnivore biologist revealed that the injuries in a fatal attack were consistent with a pack dog attack (Figure 5).

Domestic dogs are recognized but unappreciated scavengers;38 when an individual dies from natural (or not animal dependent) causes, he or she becomes part of the ecological cycle and the animal may simply view the body as a source of nutrition leading to postmortem depredation with obvious but grotesque changes and mutilations.20 This apparently simple assertion may not be sufficiently interpreted by the authorities, and the dog is unjustifiably destroyed (Figure 2). Fighting dogs are trained to attack other dogs and not people, unlike police dogs.44 Similarities between banned types and other dog breeds such as the Pit Bull and the Staffordshire Bull Terriers are apparent, and experts are needed for correct identification.

Dog bite mark analysis should be consistent with a multidisciplinary plan of action involving different forensic experts as pathologists, odontologists, veterinarians, biologists, crime investigators, and others.
