we have dogs which makes refinishing our hardwood floors very
difficult.

my wife kinda likes vinyl tile.

i dont want to ruin the hardwood by putting underlayment over it like
luan plywood.

has anyone put the peel and stick directly over the hardwood?

You're right that an underlayment would require nails which would probably
ruin the floor. In principal, you can usually get most of a peel and stick
tile up with a heat gun and a spatula. After that the floor would need more
sanding to refinish than otherwise to get up any adhesive or stuck hard
tiles.

Remove the tiles with something harsh like a 6 foot scraper bar and the
gouges you leave might ruin the floor at that time. Vinyl tiles will ruin
the surface finish but the wood underneith should be fine as long as removal
isn't too rough.

The obvious other choice is either area or wall to wall carpets. That tends
to preserve the floor as long as the installer dosen't go crazy stapling the
pad down. Small holes in a wood floor usually fill in somewhat when
refinished. I hardly notice the old staple holes or the tack strip damage
along the edge, mostly covered by baseboards.
