Blooper

About an hour into the movie, when Jessie is telling Aiden that his floors are being refinished, Jessie's scarf is tied differently within the same scene. She is shown front then back and it can be seen the scarf is different.

At the dog shelter, Jessie is wearing a gray sweater but later she's wearing a brown sweater.

Changing and disappearing leashes: Walking the dogs, when Jake gets loose, his wide, black leash changes to a narrow, brick-red lead being pulled, mid-air, to the opposite direction off screen. It later returns to the wide, black leash. Also, Jake's leash disappears while he is running.

When Jessie stops chasing Jake, the end of Lincoln's leash is around her wrist and held in her hand; however, it is not attached to the dog, as it does not descend.

Aiden says his mother made him the pillow that has a white tag at 21 minutes in. Either he is obviously and intentionally lying (unnecessarily) or it was a silly overlook in the movie.
