I don't deal with well with dogs dying so being subjected to it several times in one movie did make me cry a lot, this in turn resulted in my Alaskan Malamute throwing toys and treats at me to try to cheer me up. I know Bailey/Molly/Big Dog/Max was humanised in the movie with their perception of what's going on however I don't believe dogs are just some clueless animal and their behaviours most definitely extend past "feed me" so the behaviour wasn't that far fetched. The whole concept sort of reminded me of Fluke but in a family-friendly when.
