Domestic dog reflects its emotional status with changes in postures and vocalizations, giving helpful information about their welfare. In the present study we tested body language in dogs during positive and negative contexts and analyze the data with a web-based tool that we created to classify dog behaviors called Dog Actions Video Annotation interface (DAVAI). 51 dogs were tested in their own homes, playing with the owner and going outside to walk as indicators of positive emotional state, and being abandoned or threatened as a negative context. We evaluated the movements of tail, legs and vocalizations using DAVAI, its utility was proved because it allowed us to label specific behaviors and gave the frequency of occurrence during experimental contexts with high precision. Our results showed that there was no significant difference in dog’s behavior associated with sex. Regarding contexts, dogs in positive contexts hopping more than in negative contexts, neither bark nor wagging tail were significantly dependent on the context, specific behaviors displayed in different emotional states.
