A social media network for dog lovers based in Levin is on high alert after fielding no less than 17 different emails from people concerned for the safety of their pets.
Levin Doggy Dayz moderator Angela Ripikoi said the number of emails in the last few weeks heightened concerns there were scouts looking for dogs to be used as "bait" to train fighting dogs.
Ripikoi said people should be vigilant and watch out for their dogs.
"This isn't scaremongering. If people come to me, I have to pass it on," she said.
"This needs to be shared. The amount of emails we've had is concerning, reporting of people coming to the gate and taking photos and leaving chalk marks on the fence.
"The worst fear is that they are being targeting for bait."
