The pooches were found in Sussex and include a mix of Lurchers and Spaniels.
An investigation is underway by detectives at Crawley CID, who have been working closely with Sussex police’s specialist Rural Crime Team and other police forces, to help identify the dogs and their lawful owners.
The dogs continue to be cared for at a secure location.
Two-year-old Cocker Spaniel Willow, who was one of the dogs seized, was successfully reunited with her owners last month. She had been stolen during a burglarly in Suffolk in July 2020.
Detective Chief Inspector John Wallace, of Crawley CID, said: ‘We are desperately seeking the lawful owners of the remaining dogs which were seized in the recent warrant.
In January, Sussex Police launched a dedicated operation ‘Op Collar’, led by the Rural Crime Team, to respond to and help prevent dog thefts.
