Why this is Tauranga's most dangerous dog

A violent bull mastiff-cross has been kept in its cage for 10 months for fear it will kill someone if allowed out.
The 45kg male dog lashes out at anyone who comes near it, lunging, growling and trying to break through the bars of its cage.
Prior to being impounded it is believed to have attacked a vet, biting her on the shoulder and breaking down a door.
Tauranga City Council animal services manager John Payne says it is the most aggressive dog he has encountered in his 22 years in dog control.
"If there were no bars between you and the dog you would not be here to report on it," he told the Bay of Plenty Times.
While he had seen dogs displaying similar behaviour to this one, they usually calmed down within a week of being in the pound.
But not this one. Instead it has continued to display menacing behaviour after nearly a year in their care.
"Some behaviour is quite normal if it's in context of the situation - if the dog is threatened or challenged - but it is abnormal out of context."
After a lengthy and costly legal wrangle with the owner, the dog is now serving out its last days on death row. A destruction order has been issued and it is likely the dog will be put down in a week.
Legal costs have amounted to about $12,000.
Mr Payne, who is also the president of the New Zealand Institute of Animal Control Officers, said the case highlighted the need for a change in legislation to deal with very aggressive dogs.
The dog was impounded in July 2007 after it "nipped" a woman, but dog control officers had deemed it a threat since mid-2006 when it was classified as a dangerous dog.
"Long-winded" legislation however prevented it from being seized earlier.
The Institute had made a submission on the Dog Control Amendment Bill, now before a parliamentary select committee, seeking the right to impound dangerous dogs before they caused any harm.
Owners would still have the right to object and appeal but in the meantime everyone would be safe, Mr Payne said.
"The present position, as highlighted with our case, is that the process can be long-winded, expensive and may, on a technicality, result in the dog being permitted back into the community. This is not robust enough given the extreme threat a dog like this poses."
Mr Payne said while dogs were often the product of their environment, owners needed to remember that you could never fully trust a dog, no matter how placid they appeared.
"At the end of the day they are a wild canine species that has been domesticated. I always say: big dog, big teeth, big bite."
