Goof on the Goof
"Goofs
Continuity: When Marisa and Christopher go to the park to walk Christopher's dog, they almost walk off without her son... but also end up completely leaving the dog behind. The dog inexplicably disappears for the rest of the scene before reappearing in the hotel later."
The dog walker sent by Jerry took the dog for the rest of the walk and then returned the dog to the hotel. She was employed by the hotel.
