Although I'm more a fan of the animated Disney classics, I must admit that Disney also used to do very good live-action movies back then. This is not one of them.
"The Ugly Dachshund" is a nice comedy, full of funny moments with 4 Dachshunds and a Great Danes very well named Brutus. It's so funny how those little "sausages" cause all that mess and the clumsy Brutus destroys everything while trying to stop the "little angels" (like Fran calls them).
The destruction of Mark's studio and the party's destruction are some of the funniest destructions ever.
Officer Carmody has got to be the funniest cinema policeman ever. Not even in the "Police Academy" movies the policemen are this funny. This character is wonderfully played by Kelly Thordsen.
Mr. Toyama and Kenji are the most amusing Japanese characters ever, especially when they panic because of the "lion" (that's what they call Brutus and it's hilarious that they say "rion" instead). Both characters are greatly played by the actors Robert Kino and Mako.
I also like very much the performances by Dean Jones, Suzanne Pleshette and Charles Ruggles.
This is an enjoyable classic to watch, but it is already showing its age. It looks very dated now, especially nearly at the end, during that sequence with the dogs's show.
