The footage, which appears to show a man kicking out at a border collie and then dragging it away, was uploaded to the web on 29 December and then viewed by thousands of people.
Many alerted both police and the USPCA.
On Wednesday, the PSNI confirmed that a 43-year-old man had been arrested and that he was assisting with officers' enquiries.
He was later bailed pending further enquiries.
"The dog will be examined by a vet but appears to be in good health," a PSNI spokeswoman added.
Officers in Banbridge later revealed that the dog is called Bessie and is thought to be aged five.
A post on their Facebook page thanked the public for their help in reporting the matter and locating the animal.
"As the owner of pets myself, I understand how emotive such matters can be," the post added.
"This matter is now fully under control and managed by the appropriate authorities."
The USPCA had branded the footage "utterly appalling" and offered a £500 reward for information leading to a conviction.
