That white dog on the left looks to be of the poodle type. He will, therefore, be very smart, adroit and quick. Thanks for this picture - nice to see something positive.
I read an article back in the 1980s on "The Royal Order of Rat Catchers". Esquire, GQ, or the like.
There was such a thing in England, and in the 1960s, the British equivalent of "frat boys" at a uni managed to revive the organization, more as an excuse to party than to actually reduce the animal vermin population.
When I was a kid, my parents bought a former dairy farm that they turned into a horse property. I remember when we moved in, the barns were overrun with rats, which then used to attract big ole snakes. We were given a couple of fully grown cats and they were terrified of the rats. They were good with small field mice, but they ran from the rats. When you walked into one of our barns, there was a sort of catwalk where the dairy farmer could throw silage to his cows from above, and I would walk in there and turn on the lights and could look down to see a herd of rats sitting in one of the stalls, munching on a fresh pile of poo. It was disgusting. I got into the habit of banging on the metal feed bins when I went into the feed room to scatter them. They freaked me out. Once, our German Shepherd caught a big one in the manure pile, but it shrieked and she dropped it. She never went after another one after that.
After my dad came face to face with a 6 foot snake in the machine shed, he decided he'd had enough and put out poison. The next day, I walked in to the feed room and there were six huge rats in the last stages of dying right next to the feed bins. Never had any problems with rats after that, but it still gives me nightmares.
