You want to see brains, watch this video of my cousin, Jumpy:
He’s a Belgian Malinois, a working dog ranked as among the smartest dogs in the world. He needs lots of exercise, so if you want a dog nearly as smart as you, consider a Malinois but watch out. He thrives on work and exercise, so if you aren’t the active type, steer away from this guy. He finds sitting around watching TV boring and a waste of time. But an half hour run, great; an hour even better. This guy never stops.
Me, I like a couple of long walks a day, but in the evening, TV is just fine with me.
Oh, BTW, don’t insult a Malinois by saying he looks like a German Shepherd. There’s no match to this Albert Einstein of dogs !
