I don't really think it works that way, since we don't know what the significance is (yet), if any. To paraphrase what Chekhov himself said, if there are two guns on a mantle in Act One, there had better be a duel by Act Three. (One of my favorite uses in Phineas and Ferb is the seemingly insignificant piece of gum Buford is chewing in "Suddenly Suzy," which eventually becomes the thing that causes Doofenshmirtz's plan to backfire- I like to joke that it's the only instance in fiction so far of Chekhov's Gum.) I don't really see how a robot dog can connect to Candace and Jeremy fused into one being.
