Do you like dogs, I have had a few different breeds over the years like an Irish Setter and two Beagles.
Beagles are one of my favorite breads! I really think it's amazing how highly attuned we developed their noses to be able to hunt hares.
One of my Beagles was an expert insect hunter. She would dig them out of the dirt!
Yes they're often used by customs agencies around the world in order to detect items being brought in illegally. It's really amazing!
