Dorset Police say around 11.30am, Tuesday, April 20, a man was walking his collie at Branksome beach. They were approached by another man with a large brown dog. Police say the larger dog attacked the collie, leaving it with puncture wounds to its neck. The owner of the collie also sustained scratches as he attempted to separate the animals. Investigators believe the owner of the larger dog provided false details and left the scene without giving further contact information. It was also reported he was aggressive and abusive towards a member of the public as he walked away from the beach.
