Marvel Comics released a limited series called "Lockjaw and the Pet Avengers Unleashed." It became one of the cutest things they've ever done. The star is Lockjaw, a giant teleporting bulldog. Among the other characters include Throg, Redwing (companion of Sam Wilson), Lockheed, and Zabu. You can't forget Ms Lion, companion of May Parker. You could use standard animation or CGI; both would make an entertaining all-ages series. Everyone loves talking animals.
