Alpha reference? Maybe?
A poster in Andy's room is seen reading ALFA, vertically, from top to bottom. Although spelled incorrectly, more letters on the poster give evidence that the meaning is to shed light back onto the dog. The bottom right of the poster has an undetermined vertical subtext. The only clear letters are "GA", which can be guessed to spell GAMA, referring to one of Alpha's cohorts named Gamma .
Take a note, this is just a theory.
Andy's Game console
Anyone else notice he has the same console, but just a tad different color in his room. The 2nd movie has it above his small TV, and the third, you can see it below the TV
