His name is Jack, and it was super cute to see two beagles running around together. Jack was the "king of the ball" so they would both run after the ball and Trixie would "protect" Jack and be his wing man as he ran the ball back to his owner. It was super cute and I took a video because I'm one of those obnoxious dog owners that can't get enough pics and videos. :)
Hope you enjoy!
