The dog, a 14-week-old black female Cockapoo, has been reunited with her rightful owners after being found in an unattended caravan at the encampment. Police were initially called to the site after customers reported the presence of a large number of caravans in Chippenham, Wiltshire.

A check of the dog's microchip revealed it was reported as missing, police say.
But there were no obvious signs that the animal had been mistreated and appeared to be healthy, Wiltshire Live reports.
A spokesman for Wiltshire Police said: "Our officers have been able to return a puppy to her owners today (August 2) after she had been reported missing by a member of the public living at a traveller’s site in Dorset.
"The 14-week old black Cockapoo bitch was found in an unattended caravan by officers liaising with members of the travelling community who had gathered in the car park of Morrisons supermarket in Chippenham.
"And because it had been microchipped, officers were able to find contact details of the rightful owners."
The puppy's owners are said to be delighted to be reunited with their pet. They collected her after travelling from Dorset to a police station in Chippenham yesterday.
No arrests have been made in relation to this incident though.
Acting sergeant Elliott Alvis said: "We were able to remove the puppy from the caravan and look after her for the afternoon while the owners travelled up to Chippenham Police Station from Dorset to collect her.
"They seemed very pleased to be reunited with her and were clearly very grateful. It was nice to be able to help.”
The force was called back to the same encampment yesterday following reports of several men making threats to a member of the public.
No arrests were made then, but officers warned the group about their behaviour.
The supermarket is in the north of the town, just off a residential housing estate and adjacent to an exclusive golf club.
