Answer

I have never heard this idiom before.
A simple dictionary lookup (http://www.merriam-webster.com/dictionary/dog's%20chance)
indicates it is the lower 10% of word popularity, so I would avoid using it.

This dictionary lookup gives this definition:      a bare chance in one's favor

I could not readily find any info on the origin of this phrase.

Normally, we say "You have a snowball's chance in Hell." 
(Hell is a hot and fiery place, so the snowball will melt extremely quickly and have NO chance of survival.)
