Goof: Fred's telephone cord is missing when he and Loudrock are calling their friends about the puppies.
Juliet has 15 puppies, although you see only 13.
Loudrock lives at the back of the Flintstones. The Rubbles live on one side of the Flintstones and the Gruesomes on the other side.
Fred : It's only fair to warn you, I know karate.
Loudstone : Karate? (Lifts up a rock fence) Never heard of him. Does he live in the neighborhood too?
(After tickling Fred)
Loudrock: You kill me, Flintstone.
Fred: Don't give me any ideas, loudmouth!

This is the first episode to feature Henry Corden, who would become the replacement as Fred's voice after Alan Reed's passing in 1977. Corden is also Fred's 'singing voice' in the feature film A Man Called Flintstone.
The background music playing while Dino and Juliet secretly meet at night is a romantic version of "Twinkle, Twinkle, Little Star."
