The Border Jack experience
You know you're a Border Jack owner when...
●The stare. That unblinking, soul-piercing Border Collie stare, except it's coming from a scrappy little terrier body that's already three steps ahead of whatever you were planning.
●Watching them herd things that should not be herded, children, roommates, other dogs, a pile of shoes, with the focused determination of a tiny middle manager running a very important meeting.
●The vertical leap. A standing jump that defies physics, launched from zero to eye level in a heartbeat, because a Jack Russell spring plus Border Collie athleticism equals a dog that basically flies.
●That moment when you realize they learned the trick on the second rep and are now bored, staring at you like 'Okay, what's the advanced version? This is beneath me.
●The zoomies that have a route. Not random chaos, a calculated, optimized sprint pattern that somehow incorporates every piece of furniture, executed at a speed that makes your head spin.
