Rookie the Batdog is one of the most popular employees of the Trenton Thunder.
Rookie the Batdog comes from a line of important doggos around Arm & Hammer Park in Trenton, New Jersey.
He is the third generation of Golden Retrievers to work with the Eastern League’s Trenton Thunder, the Double-A affiliate of the New York Yankees, arguably the most successful franchise in all of pro sports.

Rookie is one of the most well-known sports dogs on the internet, and can be followed on both Twitter and Instagram at @BatdogRookie. He, along with his caretaker Eric Lipsman, the Thunder’s Senior Vice President for Corporate Partnerships, talked to Dog O’Day in an email interview earlier this week.
Dog O’Day – Rookie comes from a line of batdogs, right?
Eric – “Rookie’s grandfather Chase was our original batdog, who started with us in 2002. He passed away in July 2013. Rookie’s father was Derby, who started with us in 2010 as he shared his batdog duties with his dad. Derby passed away in January 2018. Rookie shared the batdog duties with Derby in 2016 and 2017.”
So as a batdog, what are some of your duties?
Rookie – “I get the bats during the first inning of every game, then do a meet and greet with the fans on the stadium concourse. I like to play with the Thunder players on the field before the game, and I bring bottles of water to the umpires on hot nights.
“On fireworks nights I hang in the office until after the fireworks are over because I don’t like the loud noise they make. Once the fireworks are over I go out in front of the stadium and say goodbye to the fans as they leave.”
Who are some of your baseball heroes?
“My dad Derby is my hero. He taught me everything about baseball and being a batdog. I have made a lot of friends on the Thunder; Gleyber Torres, Greg Bird, Clint Frazier, Kyle Higashioka and Domingo Acevedo are five of my favorites.
“I also hung out with Nick Swisher and Tim Tebow last year. That was fun.”
How did you strike up a friendship with other internet sports dogs like Ranger?
“I invited Ranger (@NYRPupOnAPath) to come to one of our games last August and he came here and we had so much fun. We ran around the office, played Tug of War with my toys, and played on the field before the game. I hope he comes back again this season.
This is my good buddy Ranger, he came to visit me here at the stadium...and I'm going to visit him @NYRangers during Hockey Season. #Playtime https://t.co/J70i53PLwL

“I would love to meet some of the other NHL dogs. [Vegas Golden Knights fan] Bark-Andre Furry (@BarkAndreFurry) and I follow each other on Twitter. My hooman met him and Sir Winston Da Doodle (@WinstonDaDoodle) in Las Vegas and told me how great they were. I love their tweets, and hope we can all meet in person some day.”
How do you type without thumbs?
“I use both paws and occasionally my nose.”
What are some of your favorite ballpark snacks?
“When I walk around the stands, I love the smell of hot dogs and popcorn. But since I don’t eat hooman food I have a whole bunch of treats in my office for when I come in from the stadium.”

Eric, what is Rookie’s personality like?
Eric – “Rookie’s a combination of his dad and granddad. He loves to be around people, especially kids. He’s a very happy pup who always is running around the office or at home with one of his favorite toys in his mouth.
“He loves to be with other dogs, especially other Golden Retrievers, although his best friend is a German Shepherd named Sawyer who is in the office building next to the stadium. They play together every day at lunchtime.”
If you could meet one famous celebrity, human or dog, who would it be and why?
Rookie – “I’ve met [actress and Sports Illustrated swimsuit model] Brooklyn Decker and [NASCAR driver] Dale Earnhardt Jr here at the stadium.
“I’ve love to meet Captain America. Chris Evans, he’s always tweeting about his dog Dodger. And Emma Stone! Her dog looks like he could be my brother.”
The Thunder are an especially dog-friendly organization, even by the generous standards of Minor League Baseball. (Other teams with puppers that we know of include the Myrtle Beach Pelicans and the Frisco RoughRiders, and Jake the Diamond Dog is a frequent guest presence.)
Trenton, in partnership with local animal hospital Northstar Vets, has an adoptable “Dog of the Day” (hey, we like that title!) featured from local animal rescues for each and every home game. They also work closely with the Delaware Valley Golden Retriever Rescue (DVGRR) when there’s dog days during Bark in the Park (similar to Paws and Pucks in hockey).
For the 2019 season, Bark in the Park will be on Sunday, August 11 against the Nationals affiliate Harrisburg.Senators. Fans’ dogs are also welcome to come to the stadium on Tuesday, May 21 against the Red Sox affiliate Portland Sea Dogs, when the Thunder are giving away a Rookie bobblehead, and on June 24 against the Phillies affiliate Reading Fightin’ Phils, when the Thunder are giving away a Rookie travel pillow.
The Trenton Thunder begin the year at the Tigers affiliate Erie SeaWolves on Friday, April 5, and their first home game is Friday, April 12 when they host the Sea Dogs.
