The SPCA is appealing to the public for information after a dog was found in Christchurch with multiple rubber bands around his testicles.
The dog was found in Bishopdale Park on Wednesday and it appears to be an attempt at DIY castration.
An SPCA spokesperson said as a result, he had a swollen, bleeding, smelly necrotic mass.
He was taken immediately into surgery, where he was castrated under anaesthetic and was now much better, and expected to make a full recovery, they said.
