This video was taken by Luca, president of Anpana, the Italian galgo rescue association currently visiting Pepis Dog Refuge in Pedrera. He took this film on the drive down from the village to the refuge. The second half of the video is taken from Pepis. Check out the speed of the vehicle.
I witnessed similar ‘training’ when I was there, man on quad bike with 4 galgos. This was made illegal in Andalucia but a couple of years back the Junta rescinded the law.
