The Flintstones actually had two pets, Baby Puss (who appears in the credits but only in a couple of episodes), and Dino (DEE-no) a Snorkasaurus - which is a totally unofficial, made-up type of dinosaur.

Here's the second of two Dino's included in Ferrero Italy's Flintstones Set 1. This one has a separate bowl with removable bone.

For some odd reason, Ferrero Italy decided to include two Dino's in Set 1. Okay. It is what it is. This figure shows Dino breaking out of his dog house (only the roof of the doghouse was part of the set, the rest is implied).
