DOG owner Harry Dewhurst found to his cost that man's best friend is not always so faithful.

After accidentally stepping on his pet pooch Benji, Sunday football league secretary Harry ended up in hospital, where he required micro-surgery for a gash in his hand.

Benji, who Harry had owned for 12 years, did not react when 67-year-old Harry stepped on his head, but attacked him when he stroked him to apologise.
