You'd be forgiven for thinking pet owners should be wary of giving their dog meals that appeal to its inner wolf.
But dog food produced in Christchurch mimicking the diet of the grey wolf is proving a hit with pet owners in 19 countries around the world.
K9 Natural Food sells raw pet food that "replicates nature" and has grown by 300 per cent a year since it began in April 2006.
The idea of raising a domestic pet on a wolf's diet was born after K9's founder and former police-dog handler, Geoff Bowers, studied Alaskan wolves and noticed they were far more athletic than the dogs he worked with in Britain.
After migrating to New Zealand in 2003, Bowers launched a company making pet food modelled on what wolves consume in the wild.
