Continuity mistake: Spot finds four other humanlike creatures and goes to them. Arlo is standing several feet in front of them. He begins to push some dirt by using his nose. A close-up then shows him using his nose to draw a circle around the five others but he is standing much too far away to be able to do this.
Question: When Arlo and Spot first see another human, Spot moves toward that human as if he was willing to join him to bond as a family. Arlo stops Spot from approaching the other human and places him on his back so to continue taking him home. Arlo decides he wants to share his family with Spot and keep him safe in his family house. By the end of the film, the same human Arlo and Spot saw in the distance earlier shows up along with his family. Spot joins the family. Why does Arlo decide to let Spot go this time?John Ohman
