The Dachshunds were stolen between 11.45am and 2.10pm on Tuesday 21 August 2012.
They are both girls, Roxie aged two and Queenie aged six. The both have smooth, black and tan fur.
Sergeant Matt Hagen, said:
Roxie and Queenie’s owners are absolutely distraught at the loss of their beloved pets and I am appealing to anyone who can help us find them to get in touch.
We would particularly like to speak to the occupants of a blue Mercedes Vito panel van which was parked near to the owner’s home on the afternoon of the thefts, as they could have vital information which could help our investigation.
Queenie has been suffering from a severe slipped disc and needs daily medication to help contain this condition. Without this medication her back legs could collapse.
Anyone else who knows anything about the thefts or knows the whereabouts of the two dogs is asked to call police urgently on 101, select option 1 and ask for Cheryl Power. Or you can call Crimestoppers anonymously on 0800 555 111.
