I would not advice any working dog man to let RSPCA scum on to their property if you give them a inch they will take a mile,at the end of the day there a so called animal charity ,no right to investigate any gob shite grass complaints that is the job of the police,if police turn up with warrant read it if it does not state RSPCA to be on your property don't let them.they relie on people thinking they have same powers has the police that's why they dress like them.
