PETDOING — BEFORE YOU SHARE A PET PHOTO
[ ] Read collar tags, labels, screens and paperwork
[ ] Check reflections and the edges of the frame
[ ] Review addresses, plates, badges and window views
[ ] Get permission for other people / private spaces
[ ] Check location metadata on the exported copy
[ ] Remove exact routines and unnecessary contact details
[ ] Label illustrations or AI-generated images honestly
[ ] Make sure the animal was comfortable during the photo
[ ] Reopen the exact file you intend to upload
[ ] Inspect the post after publishing

If something should stay private, leave it out.
No checklist can guarantee that a public image reveals nothing.
