I've been meeting a LOT of different dogs lately and today's shelter visit made me start to think about what makes a "trainable" dog. I'm pretty sure it's not brains, because the two smartest dogs I've ever had were also the hardest to train. So I thought I'd ask: if you've had what you consider a highly trainable dog, what were the traits that made him/her so trainable? And if you'd had a doggie school class dropout, what made him/her so tough? As inspiration, here's Brogan during day #2 of his service dog test, carrying one of the many objects he had to learn to carry and deliver. He HATED carrying anything in his mouth and it was a testament to what he would do for a butt scratch that he learned to pick up, carry and deliver bottles, bags, letters and even coins for his SD certification. The photo also clearly shows one his most endearing traits, the wonky eyeball - you could never be sure if he was looking at you or at the phantom cheeseburger over your shoulder.
