The Shaggy Dog

Preteen Moochie Daniels just wants a dog, but his dad, Daniel, is allergic to canines, like Bundles, the shabby sheep dog of neighbor Charlie Mulvihill who secretly trained his pet to help him steal jewels. Mooch's big brother Wilbert 'Wilby' is smart, shy and a promising inventor, but hopelessly clumsy when it comes to girls, and is jealous of his slick mate Trey who has no problems. (imdb)
