in Argentina but he ran away back to her

When stray dog Rubio first set eyes on German flight attendant Olivia Sievers he decided he would do whatever it took to make her his new owner.

Ms Sievers had shown the neglected dog kindness when she first met him in Buenos Aires over six months ago.

The animal lover gave him some food and from that moment on he began his campaign to become part of her family.

Rubio waited outside Ms Sievers’ hotel with his big puppy dog eyes every night.

'I tried to change my way as I didn't want him to follow me to the hotel but it was not possible he always followed me so I tried [to wait] one hour but he always watched me and followed me,’ she told Noticiero Trece.

'I met him in January or February this year when I was in Buenos Aires. I was walking around very early in the morning, we played and I had some dog food,’ she recalled.

Ms Sievers was not intimidated by the stray dog, despite his stalking, and said he was ‘really happy that someone gave him attention’.

‘This dog really wants some friend and some attention, really he's always looking for a human,’ she explained.

Every time she came back to Buenos Aires, Rubio was there waiting for her.

She eventually arranged for him to be re-homed. But he ranaway and returned to the hotel to wait for her outside the sliding doors.

'Today, I am once again crying out. He was so happy and we were 30 minutes together again,' she wrote alongside this aerial photo of Rubio

Falling in love with the dog and his persistence, Ms Sievers eventually decided to bring him home to Germany and on Friday he set off around the world.

He appeared to have a nice trip and Ms Sievers said after landing in Frankfurt ‘Rubio was perfectly treated at Lufthansa Animal Lounge’ while he waited for his paperworks.

The stewardess has continued to keep fans of Rubio updated with his progress since his relocation.

Photos on her Facebook page show him visiting a lake, going for walks with her other dogs and loving life in his new home.
