Perhaps Saga should be called to round up the troublesome animals. I have been there and seen the gates open so I am not just making this up!
But I am sure there are other offensive dogs in the area too. It is a problem all over the island which is why we see mass poisonings from time to time. The folks that have to travel the roads and beaches every day to go to and from work get tired of the chasing and biting and take matters into their own hands.
Dog owners need to keep their dogs on a leash or kept within their yards.
