So your mom's dog likes riding in the car a little too much. In particular, he loves to climb out of his natural place in the backseat to attempt to squeeze himself through the steering wheel. It turns what should be an ordinary trip to the grocery store into a death-defying roller coaster ride of terror. That's why you're going to buy her this Tru-Fit Smart Harness and Auto Zip Line ($35 and up by size). Now Sparky will still have the freedom to bounce around like the hyperactive little monster he is, but within the safe confines of the rear portion of her Prius.
