Los perros domésticos (Canis Familiaris), pueden diferenciar actitudes en personas y recurrir más a alguien generoso que dio comida, vs a alguien egoísta que la quitó. El objetivo de este estudio es ver si frente a una tarea irresoluble (recipiente cerrado con comida) acuden más a alguien generoso para solicitar ayuda. Para ello, se evaluaron 10 perros domésticos, adultos, de ambos sexos y distintas razas y mestizos, contactados mediante convocatoria online. Primeramente, se entrenó la discriminación entre una persona generosa y una egoísta mediante una tarea de elección de objeto, donde una permitía comer y otra robaba comida. Luego, se presentó un recipiente cerrado durante 3 minutos en los que podían interactuar libremente con éste o las personas. Los resultados indican que el 60% se acercó a una persona y el 50% alternó la mirada entre alguna de ellas y el recipiente sin diferenciar entre generosa y egoísta. No obstante, pasaron significativamente más tiempo cerca e interactuando con el recipiente que mirando a las personas o alternando la mirada. Los perros que interactuaron más con el contenedor fueron los que menos alternaron. Ante esta tarea los perros no discriminan a quien pedir ayuda y podrían optar por estrategias no sociales.

EFFECTS OF PREVIOUS INTERACTIONS ON AN UNSOLVABLE TASK IN DOMESTIC DOGS (CANIS FAMILIARIS) Domestic dogs (Canis Familiaris) are able to differentiate people’s attitudes and resort more towards a generous person that gave them food, vs a selfish one who took it away. The aim of this study is to assess whether dogs would be more likely to request help from someone generous when presented with an unsolvable task (a closed container with food). We evaluated 10 domestic adult dogs, of both sexes and various breeds and mixes, contacted online. Firstly, dogs were trained to discriminate between a generous person and a selfish one, in an object choice task where one let them eat and the other stole the food. Afterwards, they were given a closed container and for 3 minutes they were free to interact with it or the people present. Results show that 60% approached a person, and 50% did gaze alternation between one of them and the container, without differentiating between generous and selfish.The dogs who interacted more with the container, were the ones who showed less gaze alternation. In sum, in this task dogs do not seem to discriminate who to ask for help based on a previous interaction, and are more likely to choose more nonsocial strategies.
