Television bosses have rushed to change the name of a dog in an upcoming television show after David Bain's long-time supporter Joe Karam failed to see the funny side of the moniker.

Production company The Downlow Concept has made a six-part show called Hounds, featuring a greyhound called Lundybainwatson.

The name referred double killers Mark Lundy and Scott Watson and also Mr Bain, convicted then acquitted of murdering his family in Dunedin in 1994. Mr Bain spent more than 13 years in jail before his acquittal in 2009.

His long-time advocate, former All Black Mr Karam, complained to TV3 when he saw promotional material for Hounds, which follows the fortunes of a shiftless lawyer, his half-sister and an alcoholic greyhound trainer.

"It was wrong to include David between the names of two people who were convicted of extremely bad offences," Mr Karam told The Herald on Sunday.

"But it was also offensive to the next of kin and families involved in all three cases to have this brought up as though it is something funny."

TV3 spokeswoman Rachel Lorimer confirmed the dog's name would be changed. Actors will need to be to be recalled to overdub new lines.

The Downlow Concept, in a statement, said the greyhound was named after New Zealand's three most well-known, potentially wrongly accused men.
