Darren Godfrey is in jail for docking his dog's tail with a rubber ring commonly used for lambs; a practice he copied from his neighbours and didn't think was illegal.
The 25-year-old was yesterday sent to prison for four months by Judge John McDonald in the Whangarei District Court after earlier admitting ill treating an animal and one of not seeking treatment to alleviate pain and distress.
The Whangarei SPCA, which laid the charges, welcomed the sentence and said the dog had been in agony with an infection.
Under the Animal Welfare (Dogs) Code of Welfare 2010, tails may only be shortened or removed using a tail band in puppies less than four days old.
Godfrey was also ordered to pay $2000 of the $3519 sought to the SPCA and was disqualified from owning or exercising control over animals for five years.
