Jai Jai was also suffering from some form of skin issue which had caused very odorous, oily secretions and fur loss over most of its body and would have been in severe discomfort for months prior to him being euthanised.
The court said any reasonable dog owner would have done more to care for Jai Jai, and the dog's condition would have been obvious even to an untrained person.
The Judge's said Chan's obvious neglect, failure to care and treat Jai Jai accordingly was reckless, the SPCA said.
Bob Kerridge, SPCA Auckland Executive Director, said the dog's condition was easily preventable.
"This is a very sad case of obvious animal neglect and the SPCA's view is that the dog owner should have acted before Jai Jai's health got to this dreadful state where, sadly, treatment was no longer an option for him."
Chan has been ordered to pay a fine of $3846.03 and received a 10 year disqualification order from owning pets.
