Continuity mistake: While Peter and Brian are arguing in the kitchen the side door has a handle on the right side, but when Peter insists that Brian use the leash Brian storms out of the house, and the door's hardware has changed to a doorknob that is now on the left side of the door.
Continuity mistake: At the pound, when the keeper says sentences Brian to lethal injection, Lois stands up holding Stewie. Stewie's arms are down at his sides draped over Lois' arms. The next shot is a close up to Stewie, and suddenly his arms are crossed in front of him with his hands together. (00:17:37)
Continuity mistake: The morning after the dog show, Peter and Chris are watching the news in the kitchen. Peter has a plate in front of him with two eggs and bacon on it. It is turned so that it makes almost a smiley face with the bacon towards his arm and the eggs crooked to the side. In the next shot from a different angle showing Lois in the kitchen, the plate rotates so now the egg and bacon smile is directly facing Peter. (00:10:27)
Continuity mistake: As the cop is telling Peter that leash laws are for Brian's own good, he points his pen at Peter with one hand, holding his clipboard in the other. It cuts to a different angle mid sentence and suddenly the cop is ripping the ticket out of his clipboard and his pen has vanished. (00:09:44)
Continuity mistake: After the dog show, the next establishing shot is the family car driving down the road past a fence, a blue building, and a pink building. Immediately after, the shot cuts to inside the car and suddenly the fence is gone, and the blue building has turned yellow with other buildings changing or appearing. (00:07:57)
Continuity mistake: At the dog show, Stewie starts to try to get out of his stroller before asking Meg to push him into a lake. The person on the right of the screen as he's struggling is only seen from the calves down, and is wearing blue pants and black shoes. After Meg gets up and says she'll find him a juice box, the people behind Stewie do not match up with this at all. And then in the next close up of him, there are identical legs in the same position as before, but now with black pants and white shoes. (00:06:42)
Continuity mistake: After Lois gives Brian a new collar for the show, he turns to thank her and in the reflection of the mirror, we see there is a cabinet and the shower curtain on the right side of the room. Then after she leaves the room and he puts eye drops in, the reflection is shown again and suddenly the cabinet and shower are on the left side of the room. (00:05:32)
Continuity mistake: After Peter said he tried to go on a game show, it cuts away to a scene of Jeopardy with the man at the stand holding a card. When it cuts to a close up of the man, the position of his fingers shift downward on the card, and his wrist is turned down. (00:04:14)
Continuity mistake: When the head Native American is saying he wishes he had a spiritual vision also, there is just his right hand man beside him and the Indian in the grey suit to his other side with nobody directly behind him. When the camera cuts to a wide angle from more of a distance, suddenly the fat Indian with the cigar appears behind him, then vanishes again in the next shot. (00:20:04)
Continuity mistake: When the Native Americans make ghost sounds at Peter and Lois scaring them out of the office, the chair on the right side of the screen is empty. It cuts to Peter and Lois turning to run out of the door for a split second, then back to the Native Americans in a different angle. Suddenly that chair that was empty now has an Native American in a grey suit sitting there. (00:15:44)
Continuity mistake: In the car, Peter talks about how he shouldn't have had that prune smoothie. Suddenly their car has no rear window, and the ceiling of the car is completely different with lines going everywhere and extending back down over where the rear window used to be. (00:09:24)
Continuity mistake: On the couch, Lois tells Peter that maybe Chris is the one that should be earning that badge. As she does, Peter's arm is down at his side and her hand is resting on it. It then cuts to his reaction and suddenly his arm is out in front of him with no time between shots.
