Why does my dog sense dynamite going off 3 whole minutes before it blasts?

Hi mining community! I live 2km (1.2 miles) from a quarry in canada that produces crushed stone for paving materials. They email us in advance whenever they will be dynamiting.

Every time a dynamite is about to go off, my mostly-outdoors dog asks to come in to hide in the basement (other noises like thunder and gunshots sends her running inside as well). She is a Pyrenees cross and a very wise old dog.

I get that maybe she would sense the vibration, or hear the sound before we do, but she asks to go inside a good 3-5 minutes before the blast, every time.

What is she sensing a solid 3 minutes before the blast? Maybe the smell of the chemicals??

Thanks for your time and insight!

Warning siren, you probably dont hear it from that distance, but maybe the dog does. Typically it'll be a speaker like whats mounted a police car

I'm guessing this is it. If it were related to the smell of nitro or anfo the dog would freak out when they started to load the shot.

Was wondering if she smelled something ..

Ok that makes sense and seems obvious now

Is your dog the shotfirer perhaps?

It would be the warning siren, we have one before every blast

I work on a mine and they will have a siren go off 5min before the blast your dogs probably hearing that and ascociating that with the blast that follows

They also probably aren’t using dynamite.
