So sorry you’re going through this, Mrs Johnson! I know how agonizing it is to lose a pet.
Here’s a few tips I picked up when we were searching for our lost cat:
Posters are very, very important, but you have to do them right. The best way is to get those large posterboards (available at Wal-Mart) in the neon-bright colors. Cut those in half, so you get two signs per poster.
Then, you need a picture of your dog, preferably from a side angle (makes it easier to see any distinct markings on the coat.) The picture should take up a whole 8 1/2 by 11" paper, with a white border around. Tape/glue this to the posterboard.
Then, in huge black letters put the words “Lost” “Reward” and your phone number. Don’t specify the amount of the reward, you don’t want to discourage people who think it’s too low, and if people think it might be huge, maybe they’ll keep more of an eye out.
In smaller letters, make some kind of emotional plea like “Can’t sleep, can’t eat, please help!” This makes people remember your poster, and of course, makes them want to help.
There’s also a trick on how to hang the posters, depending on what kind of area you live in. If people are going to be driving by your posters, they’re not going to have time to take in all the info in one go. So post three in succession, like on telephone poles or whatever. First one to catch their eye, second one to give them the gist, third one to cement the info in their heads.
Also put them up on stop signs and intersections. You want people to have time to really absorb the info in the poster.
If you live in/near an apartment complex, put them up near the mailboxes. Everyone has to check their mail.
I’ll post more if I can remember anything else. I hope this helps you find Princess soon!
