Dogs are hunters by nature. "Sporting" breed or not, most still display some degree of their original predatory instinct. Terriers "worry" the prey they go to ground to catch. Sighthounds pursue or point. Labradors retrieve. Scenthounds track. Unbeknownst to most, despite their AKC distinction as a "nonsporting" breed, Frenchies have a unusual field skill: they taunt.
Like a great cat playing with an antelope before it goes in for the final kill, Brutus will relentlessly tease & taunt any creepy-crawly he can find. It's all about the fun of the chase, not the kill itself. If any small movement catches his eye, Brutus will snort around, pounce on, paw at, and (alas) eat any unfortunate invertebrate that crosses his path. Sometimes their fate is to suffer the wrath of his digestive tract, other times they are left to wither away when they cease to amuse their mighty hunter.
Nothing short of a video clip can suffice to demostrate the mighty predator in action. That being said, I proudly present today's feature film: Brutus, The Great Ant Hunter.
