Dog-assisted interventions (DAI) are those that include specially trained dogs in human health services. Often, the training methods employed to train animals for DAI are transmitted between trainers, so the latest scientific research on dog learning and cognition is not always taken into account. The present work aims to evaluate the impact that the main theories on the evolution of the dog have had both in promoting different training methods and in the relevance of behavior in the evolution of the skills of actual dogs. Then, an integrative method for the training of dogs is presented. This method takes into account the research on dog learning mechanisms and cognition processes, and effectively promotes the development of desirable behaviors for DAI during the dog's ontogeny.

Classical conditioning allows relating the fundamental research in non-human animals with contingency assessment tasks in humans, given that animals judge the relationship between a conditioned stimulus and an unconditioned stimulus in a way akin to humans judge the relationship between a cue and an outcome. Classical conditioning has been traditionally explained by associative models, but these models have been demonstrated have some limitations. Signal Detection Theory (SDT) can be a more appropriate alternative. In the present experiment contingency assessment is analyzed in four groups of rats that were exposed to a tone that was always followed by food (100%), and a tone-click compound for which different contingencies of reinforcement were employed (100%, 66%, 33% and 0%). The general design was A+/ AX+. The group in which the compound was always reinforced (100%) showed augmentation and blocking. In contrast, second order conditioning and conditioned inhibition were observed when the compound contingency reinforcement was 0%. The results showed that these phenomena appeared in different moments of training for the mentioned groups, whereas groups with intermediate reinforcement (33% and 66%) showed intermediate results. Results are analyzed using associative learning methodologies and TDS techniques. Theoretical implications of applying SDT to associative learning are discussed.
