Sniffer dogs find a living person "hidden" in the Sanctuary
In general people are unaware of the extraordinary gifts the Creator has given to animals, including pets. Did you know that a dog has about 220 million olfactory cells while humans have only 5 million on average? It is so accurate, they can know if a smell comes from the left or right, at a distance of 1.5 km and even detect emotions from its owners, when smelling their hormones.
Aware of this canine power, the police train some breeds of dogs to locate, through their smells, survivors, drugs and hidden people. That's what happened in this case on a pope's visit to the U.S. in 1995. As he passed through the city of Baltimore, he decided at that moment to go to the chapel of the Blessed Sacrament during the seminary of St. Mary.
In situations like this, the police escorting the holy priest has the routine of inspecting the entire place before he enters, to avoid any kind of attack by someone who may be hiding, placed some explosive, etc. They then carried sniffer dogs trained to find people in natural disasters and landslides (i.e., they could be metres below rubble without anyone knowing).
They let the dogs out in the chapel. They passed their snouts in every corner, every chair and image, without reactions. Finally, they arrived in front of the Tabernator.... What happened is fascinating:
The dogs were left in a position of alert, with stares at the Tabernator. They still made grunts as they felt the constant smell coming from that place, refusing to leave. For the animals, there's someone alive there, hiding! All according to the training they received to do when they located survivors in rubble.
We Catholics know what the dogs have found: Jesus alive and risen in Flesh and Blood in the Eucharist, within the Tabernary! The pets only left the alert position when the police gave them a specific order to do so.
Animals are innocent and fascinating creatures of God. His very existence bless him and give him glory, even though they are unable to understand Him (cf. Dn 3:79-81).
