An Australian guard dog names Axel, has been fitted with titanium teeth to replace the real once he lost and to effectively guard his post at a Melbourne prison.

With his new titanium teeth, expect Axel to readily sink his teeth to any prisoner who may be thinking of escaping.

Veterinary dentist David Clarke fitted the teeth to Axe after the dog damaged his teeth while biting into his bed board.

Clarke said, "So much is spent on training working dogs that it ends up much cheaper to repair a dental problem than retire the dog. Prison dogs, police dogs, hunting, quarantine and customs dogs often suffer injuries in the course of their job."
