i did spay my dog... my dog is about 1 or 2 years old when she went missing.
My dog didnt live in a cage, my house has huge compound for her to run around. Occasionally i got walk my dog, but not frequent, averaging twice a week, but thats like a 5mins walk lah.
Firstly, she was spayed. Secondly, before she went missing, she is still quite attached to me IMO. Like when i come home, she is way over excited that type. Also, i didnt see any sign of separation or dislike about me when she is about to go missing.. Maybe got sign, and i missed it? 

everyday, there will be ppl feeding the stray (sometime my mum do it    ), so the food wont be that scarce i think.
Break one leg? For real? or you just trolling.

I did yell her name, but somehow, no reaction or perhaps, maybe i overthink cause somehow i feel she doesnt want to look at me, and i when i try go closer, she went abit aggressive mode and try to bark already.
