I need advice about installing linoleum extending up a wall- which is the best way to deal with corners.?

Question:I need to install linoleum in a small area 7' x 8' rectangle. The linoleum is felt backed (to protect the laminate floor beneath - laminate can be ruined with moisture). This is temporary so I do not want to use glue. I need the linoleum to extend up the wall about 8 inches. I can bend it and temporarily affix it to the wall but I need advice about the best way to deal with the corners to prevent any moisture from getting underneath (like seeping through the corner and underneath). Strange question but I would appreciate any advice. (This is to temporarily protect the floor for a few weeks for some small puppies as it is impossible to always clean up messes immediately - the linoleum will be removed and disposed of after). Thank you for your input.

Answers:
how about putting caulking in the corners to seal it. Just besure to use it to connect the linoleum and not get on wall.
