Corrected entry: When the Russian Blue gets hit by the door he drops the remote control, and when the door shuts he drops it again.
Corrected entry: The Russian Blue Cat places the 60 second timer on the Lab door at 40 min 40 sec. It reaches 1 second at 43 min 51 sec a total of 3 minutes and 11 seconds later.
Corrected entry: Near the end Mr. Tinkles throws the formula on the kid that makes humans allergic to dogs. When Lou the dog comes and saves him and his family, he never sneezes again, not even when he puts his face onto the dog after the building blows up.
Corrected entry: In the scene where Lou is in Mr Brody's lab and hits the soccer ball, causing chemicals to spill all over the allergy formula, Mr. Brody tells his son to go to school. Well, in the previous scene, we see the boy and his dog playing for about 2 hours, and its is already the afternoon. So it would be around 3:00-4:00pm. A little late to go to school don't you think?
Corrected entry: The license plate on the van that kidnaps Buddy says "The Union State." There is no state with this nickname.
Corrected entry: In the scene where the building is about to blow up, I don't know why the crew did this, but the "brick" building buldges out like it's under high pressure. Then the roof blows out like a banana peel. In reality, since the door was open when the Brodys ran out before the explosion and when Butch drags Lou out of the building afterwards, the fake snow should have leaked out of the door and broken some windows. Also, there is a suspenseful scene where Butch is rushing to find Lou. If this reality were to occur, Lou would have been buried in the fake snow as well as Butch, making it nearly impossible to escape the building in that short amount of time.
Corrected entry: When Mr Tinkles is sitting on Mr Mason, his heart fails and the woman hits his chest. Mr. Tinkles jumps off, but in the next scene he is back on his chest.
Corrected entry: Throughout the film, Lou changes from being a puppy to an adult dog. Puppies have a "bald patch" on their stomachs and when the boy is scratching Lou's stomach there is no hair on it. In the scene where you think Lou is dead, he is lying down and you can see that there is hair on his stomach.
Corrected entry: After the Russian cat throws the spike-shooting ball into the room, a real cat walks into the room, it cuts to Lou and Butch, and then cuts back to the cat, now CGI, wearing a belt. Where did the belt come from?
Corrected entry: The dog flies through the window and knocks over the lady with the berry pie (straight out of the oven), and the lady gets pie all over her face. Less than thirty seconds later she is shooing the dog out the french doors. If you look closely you can see a few pieces of dry pie crust on her face, but she should actually have had pie filling all over her face, neck, collar, and hair. She wouldn't have had time to clean it completely off. Further, if the pie actually came out of the oven, it would still be extremely hot (cooked at 350F) and the resulting burns would be severe.
Corrected entry: When Lou is first brought home, nameless, he has a name tag on. Did the mother know what the dog was going to be called before it was given a name?
