I hadn't seen this version before - I had previously subtitled the 2007 adaptation ("The Dog Door"), which I quite liked and which is closer to the original story (although this one shows that begging was the cause of... a certain unfortunate event... while that one didn't).

On the other side, the pacing of this one is much more relaxed, while that one moves very quickly, perhaps too much so for many people.

Ultimately, both are good, but this one is probably more suitable for younger viewers (partly because the main character is changed to be the puppy).
