In phase 2, a target sample without food odor was placed amidst blank samples. In phase 3, a target sample was placed amidst control samples. To pass to the next training phase, the dogs had to have 40% of correct indications within 100 trials, without any false positives, misses, hesitations or having been giving a prompt by the handler. Significant individual differences were found in the dogs' performance during the training. The percentage of trials needing prompts to achieve independent work decreased in older dogs in consecutive training phases and increased in phase 2 in younger dogs. Increasing the level of the challenge in consecutive training phases resulted in higher percentage of false positives and misses. Although all dogs achieved the criterion of 40% correct indications in all training phases, a decreasing motivation to sniff the odor samples was observed in younger dogs in training phase 3. We concluded that operant conditioning of dogs for detection of odorants associated with cancer diseases is relatively easy; however, the percentage of false positives and misses is difficult to reduce.

Both continents face challenges and opportunities for managing human-wildlife conflict at the junction of livestock production and wildlife conservation. Predation of livestock and disease transmission between wildlife and livestock is an ongoing and escalating worldwide issue. In order to manage this conflict, producers need effective tools, and they have used livestock protection dogs (LPDs) for reducing predation for well over 2000 years. We review the history of the use of LPDs, including the loss of information on their use and the paucity of scientific research on their effectiveness. We discuss the potential for LPDs to be integral components in modern-day livestock husbandry and outline future directions to pursue.

Historically, livestock protection dogs (LPDs) protected domestic sheep and goats from predators based on development of a strong bond between protected and protector. Within reason, developing that bond between a LPD and other species of livestock should be achievable. We conducted several studies in which we raised and bonded LPDs with bovine calves and evaluated them for protecting cattle in a variety of settings. Though successful strategies in developing LPDs to protect cattle were similar to those established for sheep, we found differences that were important for optimizing the process. Here we outline our strategies for developing LPDs for maintaining separation between cattle and wild ungulates that are reservoirs of disease that cattle are susceptible to as well as wild carnivores that are predators of cattle.

Only brown bears survived as a relict population in the Italian Alps. The recent increase in the populations of large carnivore all over Europe has also affected the Alps and Switzerland. The four species discussed here are coming back: the lynx and the bearded vulture through re-introductions, the wolf and the brown bear by natural immigration. Their reappearance also revives many of the potential conflicts between humans and large carnivores. We describe briefly the history of the extermination of the four species in the Alps and in Switzerland and their recovery at the end of the 20th century, and define the most prominent reasons for conflicts. The red fox has never disappeared from Switzerland. However, the population developed very dynamically duri...
