The Jetsons shared their home with a large, Great Dane type dog named Astro that Elroy found. While George Jetson was originally reluctant to have the dog in his home, when Astro was able to stop a cat-burglar in the apartment, George decided to keep him as a part of the family. He is able to understand human language, and to some extent, he can even speak some rudimentary words and phrases. Eventually, Astro’s original owner, a millionaire by the name of J.P. Gottrockets, comes to get the dog, who he had originally named Tralfaz. When he sees how closely bonded Astro is to the Jetsons, he chooses to make the dog happy and let him stay with them.

Boston Red Sox pitcher David Price also has a dog named Astro, and although his French Bulldog is a much smaller canine than the Jetsons’ canine companion, he still heaps just as much love and attention on his little pooch. The little dog has been part of David Price’s family since he was pitching for the Tampa Bay Rays and Astro is frequently featured on Price’s social media accounts, particularly on his Instagram and his Twitter accounts, and due to his personable nature, he has gained quite a following. He was given his own jersey and was even honored with his very own bobblehead doll when Price was with the Tampa Bay Rays. David transferred teams several times, and when he left the Toronto Blue Jays after signing a seven-year contract with the Boston Red Sox in 2016, Astro was also welcomed into the fold as well. The transfer from Toronto to Boston was not without its stumbling blocks, however; specifically the ability to get Astro to Boston in the first place. Boston Terriers, as a snub-nosed breed of dog, are banned from flying on the majority of airlines due to safety concerns, including Delta and United Airlines. Fortunately for both of them, the official Boston Red Sox mascot, Wally, extended an offer to come and pick them up so they could get safely to Boston. Astro and David Price finally did make it into Boston, and Astro is now enjoying his favorite activities while in Boston, playing fetch and tug-of-war with his pet parents, napping, and sunbathing. In 2019, David Price decided to change his uniform number from twenty-four to number ten, at least in part due to his beloved pup turning ten.
