The small pic is the cretan hound for you
The others are dogs from tanzania, the shaggy one is a herd / guard dog named Simba belonging to our masaii, these are very game and very loyal - they have to be dealing with hyena etc. They are mainly guards as the masaii dont eat game but can be used for hunting.
The others are our yard dogs in zanzibar, they dont really have a job except guarding the house but the same kind of dogs from the village are used for hunting dik dik, which are very small antelope, and feral pigs.
