My two Chihuahuas are Jack, who is 4 years old, and Larry, who is 6. As we were moving back to Wyoming from Arizona in my 2016 Forester, we stopped along the way during the 2,300-mile trip somewhere. The boys always sit in a dog booster seat so they can see out the window. Jack is a seasoned traveler, because, as an emotional support animal, he has been traveling with me by either car or plane since he was 3 months old. He’s always willing to go anywhere I go, regardless of transportation mode!
