Jacob Welsh, 20, from Geelong in Victoria, raised the money on a popular crowd funding website to bring the dog, which he named Chance, back to Australia.
After failing to find a home for the dog in Greece, Welsh launched a crowdfunding page GoFundMe to pay for her flights, vaccinations and quarantine.
He had set up a 3000 dollars target which crossed within two days and reached 5334 Australian dollars, 9news.Com.Au reported.
"I gave her a little pat and ever since then she has followed me wherever I go," he wrote in a Facebook post on yesterday.

Welsh said he then snuck her into his apartment and tried to find her a home ahead of his return to Australia, but no one wanted to take her.
"The sad reality of her going back on the streets is becoming more and more real as my time left in Greece comes to an end," he wrote.
"Australia's laws are very strict with this kind of thing but I have done the research and it is possible, just very expensive. If you can spare a few dollars, Chance and I would really appreciate it," Welsh wrote.
More than 13,000 people reacted to his post, and it was shared more than 3000 times. Welsh has since taken to Facebook to thank his supporters.
"She will not spend another night on the street thanks to all the help we've received!" he wrote.
