Ariel, a kerusha born with six legs who was left in a supermarket parking lot, has had a successful operation and two of her extra limbs have been removed.
This female cocker spaniel became famous when news broke that she was found in Pembrokeshire, UK in September.
Around £15.000 was raised in donations from people all over the world, enabling her to undergo life-changing surgery.
Surgeons managed to save all four of her "normal" legs, although it was feared that one of them would have to be removed.

Mikey Lawlor, founder and manager of the Greenacres shelter near Haverfordwest, took Ariel in after seeing her abandoned, skinny and scared.
"The vet who performed the first examination noticed that, in addition to two extra hind legs, Ariel also has two vaginas," said 42-year-old Lawlor.
He added that the scanner found that he had only one kidney, which further complicated the treatment.
"Since she has two hips on one side of her body, her pelvis has not developed properly.
"As a result, her regular right hind leg had no muscle tone, so there was a possibility that she would remove that as well.
"Fortunately, that didn't happen, because the leg got significantly stronger during the previous months," he explains.
Ariel, who was named after the cartoon character The Little Mermaid because her two hind legs partially joined resemble the Disney character's tail, underwent surgery at Langdord Clinic in Somerset on Thursday.
"She had two operations that lasted about two hours, but both went well," says Lawlor.
"The next day she woke up, she was walking, eating and drinking.
"Now we just have to hope he doesn't get an infection, but he's really in the best hands," he added.
Lawlor says he hopes to release her from hospital at the weekend and be taken in by foster carers in West Wales.
"After a few weeks of physiotherapy and recovery, we will consider the option of finding her a permanent home.
"The reactions to her story are numerous, among them are calls and emails from faraway parts of the world, such as New York and Australia, which is great - I have no doubt that we will adopt her.
"I can't thank everyone who helped her enough," he says.
Director of Langford Hospital, Vicky Black, says "Ariel is a complicated little dog, whose care required the cooperation of several specialist teams such as orthopedists, soft tissue surgeons, anesthetists and radiologists".
"As part of the University of Bristol, we are committed to lifelong learning and are proud to innovate and treat animals like Ariel.
"We are delighted that such a wonderful animal has successfully recovered from the operation," she points out.
