I don't know a whole lot about it, I can't find previous threads. I don't know what you have already done.

But I agree, I'd take someone with you & go to your friends neighbors or your friends unexpected & see.

You can hang up flyers in most stores, gas stations, vet offices, street poles etc...

Call ALL area vets, humane societies, kennels, police etc...

Some papers will allow lost pet adds for FREE!

I think that add is a good one. As far as flyers go post a pic of freckles right on it.

I would not use the 1st pic though, they may get confused & think that your moms dog is the one missing as she is more visable than freckles.

Sending the best of thoughts for a safe return of Freckles!
