Wise Men Say Only Fools Rush In

Jack is thrilled to report that he has just graduated magna cum laude from the Leash University. While he had familiarity with leash subjects, he needed some time to really grasp the discipline. A few weeks of fieldwork on a regular colar-attached leash were unproductive: Mommy kept stopping every two feet and saying something about him pulling too hard.

One day a brown-suited man left a box at Jack's front door. The box contaned a weird complicated thing that looked like a bunch of strings that was placed around Jack's body and front paws. Now the walks became more confusing: every time Jack rushed just a little bit, some invisible force restrained his fore-paws. One thing Jack got out of it: Mommy stopped stressing about his every move and he could finally enjoy things around him without interruption. He just had to walk at the pace she set.

A few more weeks of advanced studies included walking with the leash dragging on the ground and obeying command "stay"in front of a wide open front door! Now, THAT's a distinguished scholar!! He is now seeking an internship at a street out of area to apply his academic skills.
Here are Jack and Tais after taking a bath, are waiting patiently before they are allowed to go outside.
