The link to the Video section is:
The name of the video is "Don Torquato de la Vieja Diana" and it shows Vice World Winner 1993 Don Torquato de la Vieja Diana on a Prueba del Campo. Note how everyone pets the dog just a few seconds after he got loose from the wild boar.
Unfortunately I couldn't see the other video on the site named "Lucha con Jabali (1991)"
