When officers were dispatched to recover the dogs, a dead fox was found in the immediate area.
An investigation is under way to identify the owners of the dogs and the circumstances in which the fox died.
Chief Inspector Mark Armstrong said: "An investigation is now under way to ascertain if any criminality or other offences were committed and I'm appealing to anyone who was in the area who witnessed events to contact North Wales Police, particularly if they have mobile phone or dash cam footage."
Cheshire Police also appealed for witnesses after reports of an illegal hunt on Boxing Day.
A force spokesman said: "We are aware of footage and reports that an illegal hunt has taken place in Allostock and consequently detectives and rural and wildlife trained officers are investigating the allegations.

"The investigation is in the early stages and we welcome further information."
Suffolk Police launched an investigation into an alleged hunting offence and an allegation of common assault after reports a fox had been killed and a disturbance had broken out between observers and members of the Great Thurlow Hunt at about 2pm on Boxing Day.
Images posted on social media purported to show the dead animal.
Inspector Jo Garrard said: "The investigation is progressing and the alleged offences are being investigated by officers in the Suffolk rural crime unit.

"Officers are in the process of collating evidence and identifying, contacting and taking statements from individuals at the scene.
"There were a large number of people in attendance and we would like to appeal to any individuals who may have left the scene, but have not yet come forward, to contact us.
"We are keen to identify and gather all available evidence which may assist the investigation."
Thousands met for more than 250 registered Boxing Day hunts just days after it was reported Prime Minister Theresa May will abandon her Conservative general election manifesto pledge to give MPs a free vote on whether to overturn the fox hunting ban.
