@ Stephen25000
Let us start with basics before getting complicated
What odor does Eddie the Cadaver dog alert to?
What odor does Keela the Blood dog alert to?
What does a single alert by either mean?
Why are the deployed together?
I await the the answer to my question first.
Now let's try you on a basic piece of simple science first.
Can you provide me with a list of compounds which these dogs can alert to ?
P.S. I hold degrees in Science, including one in Chemistry.
Here's a simple task for you.
Provide a pathway for the synthesis of Benzene from Carbon.
Please don't bother googling it, that won't impress me.
Do you know what !,5 Diaminopentane/Pentane-1,2-diammine is ?
There's a whole lot more to follow. 
ALL delaying bullshit.
THe chemical is cadaverine, dogs also react to putresine.
MY organic chemistry is 45 years post A level.
NOw stop showingyourself up and answer my questions.
I'm delaying nothing.
You clearly are getting angry.
Again you can't answer questions.
P.S. Dogs react to far more compounds than that. The ones you gave can easily be accessed from google.
So please keep trying.
I never get angry, just frustrated at people who can't give straight answers.
I know that dogs react to many compounds; I just gave the most common pair. All from memory.
Now answer my simple questionsbefore you are laughed off this board.
Let's try this again.
No more googling please, it's unbecoming.
meanwhile you aren't answering questions, merely evading, as per normal behaviour in 'mccannites' as they have become to be known.
In terms of sheer probability

you picked the two compounds which have been mentioned on numerous forums.
P.S. I'm here to stay

Meanwhile have a good evening festering on subjects you pretend to have knowledge of, but clearly don't.
