When I find pets I think owners may be looking for (very few to date) I never post all the details in the paper, and would also never post a picture. I usually write a basic description of the animal (leaving out the sex even) and write "rightful owner I.D other details". This way I know if it's genuinely the owner of the pet, it's going home, and not to a pitbull arena or lab. Better safe than sorry doing it this way. Pandy is rightfully yours IMO! You saved her life when she wandered tired, hungry, and neglected into your lives! Keep her! If any owner came forward at this point I'd fight tooth and nail to assure she never went back to that home. Mammary tumors are often caused by repeated heat cycles & also being bred. My hunch is she isn't spayed...another black mark against the previous owners.
