Before his adventure begins, Digby is given to Bill by a friendly vet, but as Bill's grandfather doesn't like to have an English sheepdog in his house, Bill is forced to give him away. He gives Digby to a guy who works in a defense lab that experiments with animals and plants for space travel. A growth-boosting chemical is made in the lab, and the animal trainer steals some to boost his own tomato crop. Accidentally, the dog is fed some and, as a result, is growing all the time; eventually, he's the size of an ocean liner. As weird animals are attractions, Digby is stolen by two well-dressed hoods and sold to a circus, from which Digby escapes, hunted by the military, both Army and Air Force! Written by MLS

the biggest howl ever unleashed
1 November 2004 | by adtroebuckSee all my reviews

quite simply the finest comedy from either side of the Atlantic i have ever seen with a dog as a central character. it seems fashionable at the moment what with all the 'air bud' movies coming out year after year, but this is where it all started. Jim dale is simply comic genius as his usual hapless self, far better than his Dr Tinkle in the carry on movies , he's given loads more to do and shows off his talents in many memorable scenes, including the legendary one where he faints at the size of Digby's doggie bowl!!!! unbelievable. Not having seen this movie for some years , i recently got hold of a copy out of a supermarket bargain basket for an incredible price and it is the best money I've ever spent. I've loaned it out to all my friends and family and we all agree that it is a truly magical film for all ages and most definitely a must see for everyone who loves laughing at dogs.
