Four puppies and several adult dogs have been stolen in a raid on a property in Walpole St Andrew.
Police say thieves smashed their way into the property between noon and 2pm on Friday, from where they took the bulldogs and pugs.
A large vehicle would have been needed to transport the animals away from the scene.
Anyone who was in the village and saw or heard anything suspicious on Friday is urged to come forward.
Witnesses should contact Det Con Richard Moden, of Lynn CID, on 101.
