What did Mr. Lincoln enjoy doing?

Laurie: is there something unhealthy about dogs sticking there heads out the window?

Debris and dirt that flies up from the moving cars can hit the dog and do damage to their eyes. The pressure of the wind (if the car is going fast) can damage their eyes. And where l live, low branches, bushes, and tall weeds can cause injuries to the dog. They may enjoy doing it, but it is not always the smartest thing for them to do.
