A dog owner returning from holiday has been left devastated after discovering her pet had suffered horrific injuries while in the care of pet sitters.

Elizabeth Ting returned home to Singapore from an overseas trip to find her miniature dog Mocha crying in pain and in immense distress.

The dog owner called the company she had left Mocha with to find out what had caused her fur baby so much trauma.

But the company sidestepped her questions, playing down the injuries, suggesting the dog had only suffered a minor injury while in its cage.

After several days without any improvement, Ting took Mocha to a nearby vet on December 7.

But her visit uncovered horrifying revelations.

Mocha had suffered a dislocated and fractured hip that could only have been caused with "great impact" and "trauma".

Ting took to Facebook to share her devastating experience, writing: "It is every fur parents' nightmare to come back from an overseas holiday to an injured dog who cried in pain until he almost completely lost his voice...

"To add a thousand tons to my already heavy heart, Dr Lee told me quietly that such joint dislocation didn't happen easily.

"I couldn't imagine the excruciating pain Mocha had suffered... unable to express his pain, cried till voice became hoarsed [sic]".

Mocha had to undergo surgery after vets failed to relocate the dog's hip after the muscle seized around the joint.

Ting went back and confronted the company who looked after her dog, but the boss dismissed claims Mocha was injured in its care, instead suggesting the dog was injured on its return home.

"No apologies, no attempt to investigate, no intention to assume responsibility... Such an obnoxious attitude," a furious Ting wrote on Facebook.

A Facebook user who commented on Ting's post shared a screenshot of an Accounting and Corporate Regulatory Authority page showing that the company no longer had a licence to operate.

Ting said she has made a police report and filed a complaint with the AVA.
