Sorry Mickshawn, I am way behind and someone might have answered already but thought you would like this link anyway. I was trying to find a definitive response on line and guess what I found on WS!! This is a great answer from Oriah with a slap by sarx

Adding this post over here, so as to try and keep the threads clean.
So how soon can a cadaver dog make a hit?
I always thought it was around an hour after death but have no idea where I heard it. I had a friend use her dogs during an earthquake so maybe from her.>
Decomp scent begins the moment a person dies. But there is a 'window' of confusion (in scent discrimination) when a scent trail turns to decomp. So for example- I go missing. A trailing dog is given my pillowcase as a scent article. That dog is trained to scent on ME (using scent particles). Then it turns out that I'm probably deceased. My other pillowcase is given as a scent article. THAT dog (a different dog) is now scenting off of the same particles, but it has been trained as an HRD dog.
At what time an HRD dog is able to accurately alert on a specific decomp scent depends almost entirely on what kind of training they have had.
One dog may be trained to detect decomp from chemical changes inside the body. One dog may be trained to detect gasses produced during decomp, and released from the body. And just to complicate further lol- one dog may be trained to detect cell(s) that have decomposed to a specific age and are unique to an individual. HTH.
(sarx is gonna slap me.)
Well, that is very interesting, since SB said that some of the dogs had made hits, but then the other dogs failed to verify those hits...
