When Rolly knocks Cadpig into the food trough, Two-Tone is seen sitting right next to him. However, in the next scene where the dogs are eating the kibble, Two-Tone is seen on the opposite side of the food trough.
In "Spots and Shots", Lucky did not want to get a shot. Sometime before "Spot's Fairy God Chicken", though, he must have learned that taking the shot is better than being sick, hence the reason he's in line to get his shot.
It shouldn't have at all been possible for Horace, Jasper and Rolly to survive the roller coaster collision. The cars really should have crashed causing an explosion, and they would have died.
Spot: Hey! This sock smells like feet! My heat's filled with toe germs! I could get sick! What is I get athlete's nose! That could lead to nasal rot!
Cadpig: She looks like a pup, but she's still her old, neurotic self.
Spot: (as a dog) Look guys! I'm a dog!
Rolly: Uh-huh, and your point is?
Spot: It's me! Spot!
Lucky: Yeah right, and I'm Thunderbolt!
Spot: No, really! I just got changed into a dog!
Cadpig: You know, there is something familiar about her.
Spot: I'll prove it's me! I'll tell you something only Spot would know; like, uh, where Rolly keeps his secret stash of fritters!
Lucky: Big deal, everybody knows that!
Rolly: Uh, they do?!
Rolly: They opened a new Kanine Krunchies plant without me knowing about it?
Spot: Do they have to clear things up with you?
(Rolly sucks up a large quantity of the kibble as well as Cadpig, then he spits Cadpig out.)
Rolly: Yuck! What is this?
Cadpig: Possibly your head after I get done with it!
Cadpig: And what did our horoscope say today, Rolly? That it was a good day to be rude!?
Cadpig: I always try to be supportive, but...GET OFF ME NOW!!!
Spot: Hey! What's going on? I'm having some sort of butt-quake!
Drumstick: That's your tail. Get used to it.
Cadpig sort of gives a hint as to why she isn't always at the top of the totem pole.
Cruella's Memo: Replace sawdust in the dog food with dirt; it's even cheaper.
Spot finally gets her life-long wish, to be a real Dalmatian, in which she becomes a brown dog with black spots. However, she eventually choses to return to being a chicken after she had time to realize that she'll always be herself regardless of what she looks like.
The title of the first episode is a parody on the title of a 1970's movie called Dog Day Afternoon.
