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.
A disclaimer on the show warns viewers the methods can be dangerous and dog owners should seek help from professionals.
"I know someone who attempted to use the technique of blocking her dog and she got bitten," Marett said.
"There is a disclaimer on this programme but people don't watch that. They do what they see. They do it by copying and learning."
SPCA chief executive Christine Kalin said the society did not agree with the trainer's methods.
"We have had a number of people contact us regarding concerns about the programme. However, as we have not seen any actual evidence that suggests a breach of the Animal Welfare Act, we are unable to actively intervene."
Veterinary Association resource manager Wayne Ricketts was concerned the dogs were not muzzled while being trained in public.
"There is a potential risk to other dogs and their owners and it is distracting for the dog who is being trained," he said.
TVNZ publicity manager Katherine Klouwens confirmed there had been "a handful" of formal complaints.
Voglar did not want to comment.
The current season of Last Chance Dogs ends on June 21 and a decision has not yet been made on a further season.
