Two Masterton dog-owners are terrified thieves from a dogfighting ring may have eyed their bullmastiff pets for kidnap.
Friends Christina Ellmers and Shorty Townsend each own a registered and microchipped dog of the breed - a 7-month-old neapolitan bullmastiff and a 12-year-old dogue de bordeaux huntaway cross.
Bullmastiffs are sometimes used in combat or as bait animals in organised dog fights and Mrs Townsend said she had been warned a fortnight ago that thieves were marking with all-weather chalk the gates, letterboxes or fences of dog owners to signal the presence of an animal that could be later stolen.
On Monday she discovered a yellow chalk mark on her fence and was planning on taking her pet to work because she was fearful thieves would nab the animal while she was away from her home.
"When I saw the chalk mark my heart just dropped. I don't feel safe any more. This just has to stop," Mrs Townsend said.
