When Fran (Suzanne Pleshette) Garrison's prize Doxie, Danke, gives birth to puppies, husband Mark (Dean Jones) uses the opportunity to sneak home a rejected Great Dane puppy he names Brutus. No angel by any stretch of the imagination, Brutus still takes the blame for the Doxies' bad behaviour. Over and over again. Until, after the destruction of Mark's art studio and the ruination of Fran's big party, he saves the day - and one of his Doxie siblings from the garbage truck.
By the end he even manages to win at a local dog show - despite not being quite convinced he isn't a doxie... If anything it was even cuter than I remembered!
It was also this film which convinced me the Hollywood separate beds were really the way to go!
