Last week Campbell Live brought you a story about beagles from a research laboratory which were being sold to unsuspecting buyers on TradeMe.
As that story developed viewers contacted us with stories about dogs that have been ill, had behavioural problems, or died after buying them off the Valley Animal Research Centre director Margaret Harkema.
Ms Harkema still has 28 dogs at a kennelling facility and has refused to give them up.
We bring you an insight into the lives the dogs had in the research centre, and we find proof that Ms Harkema has not been telling us the truth about these dogs.
Watch the video, but a warning - some of these pictures may be upsetting
