The courageous canine made a remarkable recovery and it was then Joanne decided to undertake the expedition to Everest, which was originally planned with Oscar, with Rupee by her side.
Having originally been born in the Himalayas, Rupee's vet confirmed that the pooch would not suffer from altitude sickness despite being more than 17,000 ft above sea level.
The pair were joined by Dev Argarwel, a film maker from Mumbai, who agreed shoot the expedition.
The trio flew to Delhi and entertained a quick visit to the Taj Mahal before arriving in Kathmandu and setting off to base camp the following day.
Along with porters and guides, Rupee and Joanne managed to complete the gruelling climb to base camp in just ten days.
Joanne said: "My greatest concern was wondering if Rupee could actually make it. I prepared for the worst and arranged an extra porter just in case Rupee needed to hitch a ride.
"A memorable part of the trip was seeing Rupee touch and walk on snow for the first time, he loved it.
"He played in it at every opportunity, chased it and even tried to chew it at times.
"There were many tourists climbing the mountain at the time and they couldn't believe that a dog was heading to Base Camp. They were jealous they hadn't brought their dogs with them for walkies too.
"Oscar will never be replaced and it's been difficult trying to pick up the pieces but the one thing that keeps me going is honouring his legacy and working towards the day when every homeless dog will have a forever home.
"Oscar gave a face to the masses and made us realise that even when just one dog is adopted, we may not change the world but it will change the world for that animal forever and, it might just make it to the top of the world too.
"Rupee is simply an extension of Oscar's legacy and a fine example of what can be achieved when a homeless dog is given a second chance."
