To take care of the scent aspect, you should always leave several used and unwashed laundry items around the place, anything that has made direct contact with your skin for hours.
Bedsheets sounds like a good idea, too; sleep in them for a few days and then leave them where your dog (or cat) spends most time.
Here’s an idea for added concentration: mash both concepts together, put some used t-shirts under the bedsheets for a few days and nights, sleep with them under the covers, before placing them lying around the place.
