Never heard of it, but saw this, apparently a sort of prequel to one of my favorite movies in recent years, if not ever...so I went ahead and rented it...unfortunately. It's ok, but more for kids, in my opinion. It's watchable for adults but it's really just using the name of a popular movie to get people to buy it. And for it to be called "The Puppy Years", it sure doesn't show Marley grow up much. Instead, it's all centered around training him for one competition. A couple laughs scattered here and there but not much else...who expected it to be one of those films where the animals talk? I sure didn't. I usually like movies like that, but this one was eh.
