To attract a lost dog back to the house, or to the location where you last saw your him/her and/or wherever you have a believable recent sighting, or to a food station, you can leave some of your belongings that have your scent on, on the ground. Take items from the laundry basket that have not been washed. You can also leave your pet's bed at the entrance to your property, or if lost from further afield, where it went missing from. You can also rub toilet paper on your body to get your scent on it and drop it around a small area, as that is biodegradable. Use your urine - it might sound gross, but it does work.
Set up a feeding station only at the location where you last saw your dog and/or wherever you have a believable recent sighting. A feeding station can be a largish plastic box, lying on its side, with a bowl of water and some wet food inside. You can leave trails close by, of fish oil, or Liquid Smoke to entice your dog to the feeding station.
If you think your dog is still close to where they went missing, or if you think it may be close to home, you can use a BBQ to attract them. Best food items to cook are strong smelling ones; remember you won't be eating the food you are cooking so it doesn't have to appetising to you. Late at night is a good time to have a scent BBQ, as it will be quieter and you will have less chance of attracting other people's pets, especially if you are in an open area.
