A stray dog that was found abandoned in the street with horrific facial injuries has made a full recovery thanks to a British charity.

The dog, named Kiss, was found in Chiang Mai, Thailand, semi-conscious and covered in dirt, with parts of her skull exposed by an open wound.

Even experienced vets struggled to hold back their tears at her condition, described by charity Worldwide Veterinary Services as 'the worst injuries we have ever seen'.

Heartbreaking: Kiss the stray dog was found on the streets of Chiang Mai, Thailand with crippling skin conditions

When she was found, Kiss was severely underweight, unresponsive and suffering from multiple skin conditions,

An old injury on her face had been so infected that skin and tissue had rotted away.

Maggots were living inside the cavity which also exposed her skull.

Worldwide Veterinary Services Thailand operations director Ian Clarke said: 'The suffering was unbearable to see and the injuries caused distress for many of the vets and vet nurses that came into contact with the dog.

'To think of what she must have been going through, physically and emotionally over the few months before she was rescued was enough to break the hearts of some of even the most experienced staff.'

Shocking: The poor dog also had a hole in her face where an old injury had been left untreated for so long that her skin and tissue were rotting away with maggots living inside

Helped: Vets from British charity Worldwide Veterinary Service treated the abandoned dog

Recovery: In this picture, taken just five weeks later, Kiss the dog has made a full recovery

However, during five weeks vets were able to turn her life around.

After what would have been months of suffering, her wounds were finally cleaned and sewn shut and she was given food and water.

With further medication and rehabilitation Kiss has recovered fully and able to lead a healthy, normal life.

Charity C.E.O Luke Gamble said: 'We have shared this story so that our supporters and dog lovers across the world can see the challenges we face every day here at WVS Thailand.

'Our staff work extremely hard to help the dogs of Chiang Mai and beyond and often have to deal with some very emotionally challenging circumstances of which many people are unaware.'
