Although dogs are used by subsistence hunters in many locations throughout the world, hunters with dogs have not been studied from an optimal foraging perspective. A study of indigenous Mayangna and Miskito hunters in Nicaragua indicates that the use of dogs affects both the encounter rates and the pursuit times of several prey types. Before hunters can identify the prey type and initiate a pursuit, they must first catch up to the dogs, and their dogs sometimes chase unprofitable prey types. These costs are incorporated as an additional constraint in the optimal prey choice model. The results of the optimal foraging analysis indicate that hunters generally focus on prey types that are in the optimal diet set. However, hunters do not consume two rarely encountered species that are in the optimal diet set, giant anteaters and northern tamanduas. Although hunting with both rifles and dogs increases the likelihood of harvesting tapirs, the return rates of hunting with dogs, hunting with rifles, and hunting with both guns and dogs are otherwise comparable. This study therefore demonstrates that dogs can be valuable hunting accessories.
