Even Lassie can become a wild beast

By CATHERINE MASTERS

Lassie has a lot to answer for, says dog trainer Flip Calkoen. The film and television canine star gave generations the idea that dogs know good from bad, right from wrong.

But Lassie was 12 dogs taught tricks by good handlers, says Mr Calkoen, a behaviour consultant who has worked with wolves in Europe.

He has lectured at Auckland University of Technology and speaks to posties and Inland Revenue staff about canine behaviour.

"Dogs don't know the difference between what we perceive as right and wrong. Dogs are opportunists - they respond as a wild animal would."

In dog circles, when a subordinate approaches, a dog can indicate its superiority by growling or nipping. "If they did it to another dog ... no problems, but to your child it means a scar possibly."

Mr Calkoen says even a trusted dog can bite.

"It's highly unlikely, but there's no guarantees if the dog gets a fright or is hurt or something unexpected happens."

He says people should learn how to work with their dog and provide non-aggressive leadership, which stabilises the animal.
