According to Jose Mauricio Barbanti Duarte: Its an adult female of gray brocket with her baby already in a phase of weaning. The injuries are not very clear, but these animals usually have small scratches on the face of racing in the middle of the bush. In this case, it seems that the adult female is expelling the young, a natural process in this phase of weaning and may have some fight between the two (they fight giving each other a hand) and this may have generated lesions especially in the cub. Of course this is a hypothesis only, but the scene is very interesting and curious.
