Hey Vegi .. sorry your having a bad one and hope voicing this crude helps your sholders feel lil bite lighter . You didnt mention if this is your place or not and really dont matter . but , If it is YOUR place you have every right to be upset with your renter .
You mentioned that the dog is a Bytch when the owner is gone , have you thought bout takin a lil video clip of the dogs actions when shes not there ? this giving you proof of why the dog isnt wanted in your place , The dog deserves a home where its wanted like others above have mentioned , the tenent should of contacted you to see if it was ok . but apparently that didnt happen or the dog wouldnt be there,, but anyways .. I send a huggle your way and hope for a better day for yah .. Endzy
