I wonder how long a person would have to be deceased, to leave a scent a dog could pick up on.
Seems like some amount of (horrible to say it but) decay would have to take place. Otherwise, especially in a baby's room, it seems like the room would be flooded with scents of all sorts.

It was the parents’ room near their bed.

Yeah, I’m not buying the dog’s hit. There’s no way the baby would have been left there for decay to begin. Now, if no one had seen the baby for days, maybe, but certainly not since being reported missing.

I read online that it takes about 90 minutes (an hour and a half) for decomp to be strong enough for a cadaver dog to smell it. That is not very long at all.

Yes, I was wondering that too.
