A telephone with the body made entirely out of rubber. The rubber compond used would include an odorless liquid dog repellent, which would stop it from being chewed. [link]
The circuit board inside would be made of flexible plastic, and the speaker and microphone would be made out of polyvinylidene fluoride. [link]-- Cedar Park, Apr 15 2003 (?)

History of Nokia http://www.nokiainfo.net/nokiahistory.php [krelnik, Oct 04 2004] Thermite rocket plunger mentioned in my anno [notexactly, May 13 2016] Nokia make one. All the bits necessary to achieve your goal of near-indestructibility are rubber.
Dog repellant they don't do.-- FloridaManatee, Apr 17 2003 [FM]: Nokia's is merely a plastic phone in rubber garb. We've all seen bits of rubber here and there on home and mobile telephones. The phone I propose has its entire case made out of rubber. Probably not possible with a cellular, given the amount of circuitry and batteries.-- Cedar Park, Apr 18 2003 I used to own a rubber alarm clock that you threw against the wall to use the sleep alarm. Sorry it's off base with the cellphone theme, but it was made of all rubber.-- colaaddict, Apr 19 2003 I've always been amazed at how fragile Nokia phones are, despite their popularity. My friends are constantly relating horror stories. I've dropped my Kyocera phone many, many times, from heights of 3 to 6 feet including onto hard pavement, and it still keeps going. The battery has never popped loose in a fall. So clearly some companies (other than Nokia) have a clue about how to do this right without using rubber.
It would make sense for Nokia to make this however, as the company was originally called the Finnish Rubber Works back in the 1920's! (See link)-- krelnik, Apr 19 2003 Lots and lots of duct tape.-- RayfordSteele, Apr 19 2003 My experience of Nokia phones is opposite to [krelnik]'s. Last year I dropped my 3210 down into the light well in front of my basement window (~8 feet) onto bricks and it suffered no ill effects. Previously I'd bounced my old Nokia 100 (analog thing) down my (stone) basement stairs, all ten of them, with similar results.-- angel, Apr 19 2003 Sounds like the makings of a new Olympic sport.-- 2 fries shy of a happy meal, Apr 19 2003 If they're anything like toilet dogs, a thermite rocket that shoots bits of molten metal should deal with them.
