Race dogs common site during NASCAR weekends (cont'd)

So it's not bizarre for a NASCAR fan to want to know how Clint Bowyer is enjoying puppy-hood with his new Australian Shepherd or what kind of dog parent Earnhardt is. Seemingly, Earnhardt's Boxer is a pampered pooch.

"He has his own bed, but he prefers to sleep in the big bed," Earnhardt said of Killer. "And if he gets to bed first he ain't getting up. You just have to take whatever available space there is. He's funny like that and I really enjoy having him. He's a good dog. He has the same attitude and personality that I have. We don't clash and he listens well."

For the most part, Killer goes wherever Earnhardt goes.

"When I head toward to the door, he wants to go, too," he said.

And when he does go on the road, Earnhardt said he visits family.

"Killer's parents are Greg Biffle's dogs, so at the track he always spends a couple hours over at their motorcoach," Earnhardt said. (Note: Gracie is a sister and Foster is Killer's dad.) "I feel pretty lucky to have Killer because when you get a pet the first thing on your mind is what kind of animal am I getting? Am I going to get a pain in the butt or is this going to work out? You know, are we going to get along? So I was really lucky. Killer is an easy-going dog."

Taking the family pet on the road is a recent luxury afforded to drivers since the advent of team and private planes as well as motorhomes.

For the Busches, having the dogs at the track makes the motorhome feel more like an actual home.

"They are our children because no matter how bad a day Kurt is having, he's always happy to see the puppies. They love you all the time, unconditionally no matter what happened on the track," Eva said. "They just wag their stubby little tails and are happy to be with you."

Bowyer recently brought home his new dog named, fitting to his personality, Trip.

"He's just man's best friend," Bowyer said. "He goes everywhere with us and I just really have been enjoying him. He's got a good temperament to him and good attitude and he behaves well."

For Bowyer, the dog provides an extreme amount of comfort at the track, kind of like a furry form of therapy on four legs.

"I think just spending a lot of time with animals is the best thing you can do," Bowyer said. "He's been a really good puppy so far, and little to no trouble. And you know, you couldn't ask for much more out of a puppy his age. But I have really been enjoying him a lot. He's the dog I always kind of wanted growing up, so he's quite the handful."

The dogs are a handful on the road, yes, but there's a built-in community inside NASCAR's motorhome lot filled with other pet owners willing to sit and help out when they can.

Race dogs, as Eva Busch calls them, enjoy life on the NASCAR circuit and have developed unique talents to keep them entertained.

"They know the national anthem," she said. "When the Nationwide Series race comes on and the anthem begins, tails start to wag and they run around because they know fireworks or the flyover is coming soon and they start running back and forth waiting in anticipation."

Dale Earnhardt Jr. feels at ease with Killer by his side; Clint Bowyer doesn't take a trip without Trip.
