Do you know the owner John?
Have they informed the dog warden, Police, RSPCA etc?
If they register the dog as lost here
DogLost - Reuniting Lost Dogs With Their Owners they will get a lot of help finding her. They need to print out posters and put them up all over the missing area so others are aware.
The last Beagle missing in this area was in Darwen a couple of weeks ago. He was missing for 5 days and 30 minutes before being caught. The worrying thing about this one is she is missing in town with all the traffic.
Where on Burnley road did she go missing and do you have a phone number for the owners you can PM me please so I can help look for her?
