We have a Jack Russell and a Yorkie.... the yorkie's whining has rubbed off onto the Jack and this is extremely annoying when we are in the car. They both enjoy whining for no particular reason and have resorted to even running around the car frantically. They enjoy the heck out of car rides but if we seem to approaching ANYTHING (so much as a stop sign)... they are out of control. We can be on the interstate for 30 minutes, and they are both whining NONSTOP the entire time... Any suggestions??? They go with us EVERYWHERE! Thanks in advance for everyone's help!
