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). When a dog spends a long time in chewing a bone, it turns it over and over resulting in a mass of grooves and pits from which it is difficult to discern individual tooth marks.12,25,28 Tokdemir et al stated that the impact of animal intervention on the establishment of the time of death should be calculated by taking all adverse conditions into consideration including rate of the decomposition process of the corpse, and the presence of bugs and larvae around the dead body.19, Given that any of the suspected dogs found at the scene could be involved, all of them should be examined whenever possible.8 Veterinary assistance will be necessary to examine for illness, estrus, or evidence of recent pregnancy.13 Detailed pictures and body schemas of the dogs as well as photographs of neck braces, scars, and evidence of prior veterinary treatment are useful to identify a potential dog and its owner. 7.
