The third dog in the running is a beagle that has thyroid cancer. Its claim was $14,631.
Together the three dogs have racked up over $47,000 in veterinary bills.
However dogs aren't the only furry friends receiving a hefty vet's bill.
Three cat owners made total claims of more than $8000 each.
The top cat was a 2-year-old domestic shorthair that was attacked by a dog and needed medical treatment worth almost $12,000.
Last month the Companion Animals in New Zealand survey was released, confirming Kiwis are a nation of pet lovers.
The research found 41 per cent of households have a cat, and 34 per cent own a dog.
It also found 88 per cent of cat and dog owners believe taking injured or sick
animals to the vet is a very important part of pet ownership.
In the 12 months to June 30 this year $11.41 million in claims were paid out by Southern Cross pet insurance.
