My Toli is a pinto. I've never seen anything grow so fast. They do love to lie around and they decide if they want to come, fetch or anything else you ask them to do. Mine is 5.5 months old and I've finally got him to come 95% of the time and to stop whatever it is he is doing when I yell no. Beyond that, he knows sit, stay, down, etc, he simply decideds when he will comply. If he's busy, distracted, or tired. He simply doesn't do what you ask him to do. The breed is stubborn and independent.
I wouldn't trade him for anything!
