According to the vet that treated Bear, it was remarkable the dog survived being exposed to the elements and even more surprising that he managed to crawl home.
Crown prosecutor Bridie Sweetman said the offending needed to be denounced and sought a sentence of imprisonment.
Williams had pleaded guilty at an earlier appearance but she questioned his attitude and remorse. He had tried to minimise what he had done by saying, 'it's just a dog', Ms Sweetman said.
Judge Allan Roberts described the attempt as "barbaric" and said Bear would have suffered significant pain and distress.
Judge Roberts said home detention was not considered due to the seriousness of the offending and Williams' previous convictions for violence and breaching a protection order.
The SPCA said it was pleased to see sentencing that reflects the seriousness of the offending and that Bear is recovering slowly.
Williams was also ordered to pay $500 prosecution costs.
