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

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.I need advice about installing linoleum extending up a wall- which is the best way to deal with corners.?
how about putting caulking in the corners to seal it. Just besure to use it to connect the linoleum and not get on wall.
