Beach scenes apparently set in Briny Breezes, an area nicknamed "Dog Beach" by locals for its friendliness to the canine set. Palm Beach County Commissioners banned dogs from the beach, for reasons self-evident in the last beach scene.
Early in the film, while still set in 90's, when Jen is leaving and they are at the airport, a Nissan Murano is clearly visible in the background. The Murano was not produced until 2004.
When the 'clearance puppy' is in the car on his way to home, he doesn't have a collar. However, when they reach home, he does. Again, at night, when Marley cries and howls till John takes him to his room, he (Marley) isn't wearing a collar.
When Jenny returns from Gainesville, John picks her up from the airport in what it seems to be a rainy day. Even though the water is pouring on their car, the men walking in the distance are obviously not rained upon and the asphalt is dry.
John Grogan: A dog has no use for fancy cars, big homes, or designer clothes. A water log stick will do just fine. A dog doesn't care if your rich or poor, clever or dull, smart or dumb. Give him your heart and he'll give you his. How many people can you say that about? How many people can make you feel rare and pure and special? How many people can make you feel extraordinary?

Q
Is 'Marley and Me' based on a book?
A
Yes. Marley & Me is an autobiographical book by American journalist, John Grogan. The story revolves around Grogan and his family's life during the 13 years that they lived with their Labrador retriever, Marley, and the relationships and lessons from this period.
Q
How does the movie end?
A
Marley's stomach twists for the second time. This time, the vet can't save him, and it becomes necessary to put Marley to sleep. John stays at his side the whole time until Marley's eyes close. The Grogans bury him in the yard, with each family member giving him a picture, letter, or remembrance of their love for him. The movie ends with John looking back on his memories and realizing what Marley taught him. A dog doesn't care if you're rich or poor. If you give him your heart, he'll give you his.
