"We have told nearby residents so that they can keep a close eye on their pets, because we would hate to see this happening to another animal. We are also asking for people to let us know if they have any information that may help us find who is responsible for this cruelty so that we can pass it on to the relevant authorities."
In a Facebook post, the Waikato District Council says the Animal Control team have named the puppy Sia, "(after the song Titanium) because she is bulletproof".
Sia is currently being cared for by the Waikato SPCA and is expected to make a full recovery, after undergoing several surgeries.
"She is currently receiving medical treatment but we expect her to make a full recovery. She has a loving, beautiful nature and will be rehomed when she has recovered."
"We want to find the person responsible for this cruelty so if you've seen anything please let us know so that we can pass it on to the relevant agencies. You can phone us on 0800 492 452," the team posted on Facebook.
