Dog trainers are calling for TVNZ's Last Chance Dogs show to be scrapped after claims the trainer uses dangerous techniques on dogs.
The programme, which began in April, looks at aggressive dogs on death row and the owners who couldn't control them. Dog trainer Gina Voglar works with the dogs to curb their behavioural issues and prevent them from being put down.
Napier trainer Alison Marett claimed Voglar used archaic and unnecessarily aggressive techniques.
Voglar can be seen using choke chains to control dogs as well as pinching and pulling their skin to get their attention. She also uses other animals to test the temperament of aggressive dogs, possibly causing anxiety to the test animal.
Marett was concerned inexperienced dog owners would try to copy the techniques, which could be dangerous if not done by a professional.
