Considering his failed reboot (https://www.sitcomsonline.com/boards/showthread.php?t=284147), how much of an influence was The Flintstones on Seth McFarlane? In particular, was Brian Griffin, was influenced by a proto type version of Dino? There was one episode from Season 1 of The Flintstones, in which Dino talked (https://metv.com/stories/dino-was-originally-a-talking-character-early-in-the-flintstones) and was going to be more of a butler to the Flintstones.

Instead of a pet dog, Brian is an anthropomorphic human like dog family member, which is what Dino could have been if they stuck with that version. Or was Brian more directly inspired by Dogbert:
