...only 1 at a time! Having said that, we have a friend who has 2 dogs who behave impeccably. They have set a sterling example for Mitzi, who now behaves well...without barking for France at every opportunity! Bliss!
@s4sayer i have seen twodogsincars several times, one when i didn't have the camera with me will be forever burned into the memory bank, two German shepherds in the cab of a truck, sitting in the driver and passenger seats ready to roll
they can't be much worse than many human drivers!
