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. The huge force the bite muscle complex can exhibit allows the dog to wrench and tear and cause considerable damage.2,4,6,8,9,12,13, Although there are reports in which many breeds of dogs have been involved in fatal or nearly fatal attacks on humans, the majority of cases involve pit bull-type dogs, Rottweilers, and German Shepherds, most of whom were unrestrained on their owners holdings.1,2,6,1315 The expression pit bull-type defines a group of breeds with special features and behavioral characteristics: a tendency to not to make intimidating gestures (growling and baring of teeth) prior to attacking, greater jaw pressures, a capacity to continue grinding their posterior teeth into tissues while holding on with the canines, and an aggressive personality in a relative larger size. The scattering of the clothes and removal of the genitals/genital regions of both men and women can raise the suspicion of sexual assault. Dry up spills, especially on slippery surfaces, before running or walking over the surface. Energy is lost and the fracture line stops; helps to determine sequence of breaks in bones when there is multiple fractures, Breaks that occur in bones that are weakened by disease, intermittent stress over long periods of time (dowagers hump), Blood clotting in damaged area stablizes the broken bone pieces; stimulates osteogenic layer to produce connective fibers to span broken surfaces, New veins and connective tissue will form; sharp broken bone will round due to resorption; fibrous bones forms; then woven bone forms and replaces fibrous bone; callus forms, Visible raised, irregular area; forms 6 weeks after injury; can be visible for years or be resorbed leaving no indication, 1) Tension; 2) Compression; 3) Torsion; 4) Shearing; and 5) Bending, Force pulls on bone; common in dislocations; usually along long axis, Force pushes down on bone; commonly found in skull; complete or incomplete fracture; numerous and wide reaching fracture lines; shape of weapon leaves mark on bone, Twisting; spiral fracture; one end of bone held stationary while other end is twisted; common in long bones; skiing accidents and child abuse, Force impacts bone at right angle to long axis of bone; discontinuity common but few fracture lines; may cause butterfly fracture; adults complete fracture common; subadults incomplete fractures (greenstick).

Thus, the potential for wrongly identifying a dog may result in a dog being held within kennels for long periods or a breed/type being overrepresented in incident reports.44 BSLs do not address the fact that a dog of any breed can become dangerous when bred or trained to be aggressive.14 A change in the current regulations would prevent dogs that are not dangerous but may belong to a specific breed/type from spending long periods in kennels.44 An alternative to BSL is to regulate individual dogs and owners on the basis of their behavior.14 Most of the responsibility for such attacks lies with the dog owner.7 In terms of some legislatures, a person who keeps or controls an animal in his own interest is liable without fault because he/she creates an increased risk of harm to the community.8 Generic nonbreed-specific dangerous dog laws can be enacted that place primary responsibility for a dogs behavior on the owner, regardless of the dogs breed. 2001;46(5):12321234.

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.
