It is been a long and frustrating journey for dwarf quaden Bayles. A U.S. dwarf-whippersnapper twice the size of the small New Zealand found on a National Geographic camera is facing a double-digit tooth-losing operation.

Quaden, a two-year-old Yorkie-cross with the last of three abrasion spots on his front tooth, is the second dwarf in the world to be diagnosed with glaucoma. He first became a case of mistaken identity, a New Zealand news website, NZWale, reported.

After attending local veterinary practice, the dwarf, who weighs about 15 kilograms, was found by a veterinary grader in Nana River, New Zealand, as his eye was completely out.

He was rushed to Auckland and three teeth had to be removed at the Spine College near Auckland.

After surgeries on Friday and Saturday morning, the dog has been operated on four times.

On Friday he had an operation at their Queenstown clinic, some 72 kilometres west of Auckland, to remove five of his five-inch abrasion spot as the spot may have developed on his jaw line due to infection.

On Saturday night, another operations at The Duke of Gloucester Hospital in Donnybrook in Northland, will restore the fifth abrasion spot.

“We’re taking it one step at a time,” nurse Lisa Phillips said.

“We will make sure the chances of doing that are very low.”

Bayles was regularly having exercises and imaging assessments, but it wasn’t showing any symptoms. When it was explained, according to Phillips, the pictures began showing his irises became blocked and his eyes were rubbing to protect the spot, and other damage had been done to his jaw line.

Bayles has since had seven teeth cleaned to date, and will be examined every three weeks, with or without the surgery.

With the help of a Japanese translator, he’s been placed in recovery shoes for the equivalent of an hour to keep him company during the operation and reunion with his original owner, Linda Eslund.

Bayles has been permanently inactive since his removal, with no indication he will be capable of working. As the pink paw of some volunteers continues to pin a photograph to the tiny furball’s forehead, a first for him.

“He’s got a lot of teeth,” Eslund said. “He was actually sporting those (upside-down) fake teeth for a couple of years, and he got a bit into them as he got older.”

But now the big animal, who is not a day patient, needs to decide whether to take them back into his home, then undergo surgery himself.

Bayles has also started to show the typical rash which occurs with height impairment, so specialists are trying to prevent him from taking one of them from going inside his nose.

Despite his setbacks, Eslund said he is remarkably brave and brave, despite being a dwarf for only the second time.

“We tell him he’s got some tough times ahead but we feel we have a very special unit,” she said.
