Rio came to The Donkey Sanctuary after a rescue in 2014 along with his twelve donkey friends.
These donkeys were being battered relentlessly by extreme weather, fighting for their lives, with little shelter from the wind and rain.
Now at seven years old Rio has settled in to his life of Sanctuary.
It was noticed one day in 2015 that Rio had quite a runny nose, which can sometimes be a sign of respiratory disease.
After a check-up to ensure that there was no contagious disease Rio was brought into the hospital to further investigate the problem he was having.
The tube that runs from the ears to the back of the throat, in horses and donkeys has an enlarged area called the guttural pouch.
This is an area that sometimes gets infected with bacteria - it is the site where certain types of bacteria can grow, which can cause a large amount of pus that if it cannot drain out, will swell and block the airways.
It was discovered that Rio had some infection in both of his guttural pouches, which made them swell, and he had semi-solid pus that had to be flushed out.
The procedure is difficult as the vets had to pass the endoscope up the nose and try to enter the pouches on each side of his throat.
In Rio’s case he needed quite a few sessions to help clear the areas.
After his procedures, and once he was feeling better Rio returned to Woods farm where he lives with his friends Becks, Robin and Theo.
Rio is unfortunately prone to this infection, but is lucky to have the expertise and knowledge of The Donkey Sanctuary veterinary team whenever he needs it.
