A pet shop in NEX shopping mall apologised yesterday following allegations that one of its staff members had abused a dog.

The Agri-Food and Veterinary Authority of Singapore (AVA) confirmed that it is investigating the case.

On Sunday, a customer, Jamie Thompson, posted a 10-second video clip on Facebook showing a dog being thrown into a cage by a person whose face could not be seen in the video.

Jamie, 16, a psychology student, said the incident took place last Thursday and gave details of the abuse in her post. The dog does not belong to her.

Pick-A-Pet, in an apology on its Facebook page, said "the staff (member) has been reprimanded, counselled and has resigned voluntarily". It said it had taken the dog for a full health check and posted a photo of a medical report from a veterinary clinic, which said the dog was "in good health without any physical or obvious behavioural signs of abuse".

Pick-A-Pet declined further comment, citing investigations from AVA.
