Our good news is that Roxy turned up on our doorstop 6 weeks after she disappeared! She was thin and slightly dirty but in good health. We still don't know where she went, but suspect that someone must have been feeding her regularly. Somehow, she eventually managed to find her way home. Sadly, there has been no sign of Pepper.
and I found him back today. Please do not give up hope.
What I did was:
1. Emailed and sms all all your friends in the area to spread the word
2. Post on facebook
3. Call your local majlis perbandaran. to ask if they have taken them
4. call SPCA
5. Put up flyers near your local vets. (this is what help me find my dog) the person that found my dog took my dog to the vet.
Good luck..
