The giant animal, named Sov, worked in the tourism industry for over 20 years, originally a logging elephant.
Before he was taken to his current sanctuary in southern Thailand, when he was not carrying tourists, he was chained to a roadside chain.
Now at the age of 55 she was in danger of starvation because her teeth had deteriorated so much that she could not drink food.
But after forever visiting her home, she finally formed a bond with another elephant named Jahn – and the two are often seen closing their trunks together in a captivating gesture of affection.
Bona, described as “friendly”, was transferred to last year’s veteran sanctuary following last year’s misconduct.
“Soo and Jahn, who have been friends for the past 30 years,” said George White of Charity World Animal Protection from Charity Online.
“They knew each other through time, logging together, in tourist camps, and during low season rest periods.
“When So and Jahan were followed in the giants, they were happy to see each other again.
“Their joy at being able to spend time together is evident through their constant tactile interactions and singing.
“Now whenever they can socialize with each other, Jahn and Sowe can spend many more years enjoying each other’s company.”
Due to the deterioration of his teeth, he was not able to eat properly, and anxious vraters noticed that he was becoming very thin.
George said: “Once the last set of elderly elephant teeth are no longer sharp, they cannot eat the range of food they need.
“Lack of food puts them at risk of starvation and malnutrition, or the problem of large pieces getting stuck in their digestive system.
“As Sove is an elderly elephant, he is on his last set of molar, and they have deteriorated.
“As a result, she struggled to eat a wide and plentiful diet and became very thin.”
Thankfully now that his food has fallen down, Soo enjoys pineapple leaves, sugarcane, salt and pellet food.
David Owen, World Animal Protection Consultant of Follow Giants, stated: “It is already a difference to his personality and health.
“She has so much energy, she looks so much fuller, even her skin looks better.”
The charity has warned that along with tourism due to the Kovid-19 crisis, centers supporting elephants are in grave danger.
In a statement, it said: “Elephant-friendly locations allow tourists to feed, graze and socialize elephants with each other on their own terms.
“But due to the coronavirus epidemic, tourism in Thailand has stalled, putting the lives of captive elephants in grave danger.”
