You can catch a shiny in the wild, but it is very rare. You could trade for a shiny as well, but you would usually need something really good.
You can also hatch a shiny pokemon. While this does not make your chances any better, it still works.
you could also, if you wanted to, use a cheating device. I do not recommend doing this, since there is a chance it could ruin your game. Especially if you have a bad code.
You got to go to iron island and at the end of it you find it

There is 1 out of 8000 a shiny will come up
Once you find a Shiny Pokemon just catch it and it remains Shiny forever.
you can catch a shiny in diamond pearl platinum or any other game but they are 1 in about 8000
Your Mom! Catch shiny Pokemon like a non noob by chaining!
You can't in the 3rd generation. In diamond and pearl you can catch them in wayward cave with a 1/10341 chance of them being shiny.
you can get shiny Pokemon by using your diamond/pearl game to chain Pokemon you can use your poktech to keep track of the number of Pokemon your catch. depending on how many you catch you should evetually get a shiny, or just get really really really really super duper extra lucky and run into one, but i recomend chaining. your go to gameradar and type in shiny Pokemon or Pokemon diamond/pearl how to chain Pokemon.
id say unknowns ive caght at least 5 different unknowns that r shiny
You don't. If a Pokemon is shiny, it remains shiny forever. If it isn't shiny, it will never be.
it is very rae to find them but if your lucky enough you will find one i did insted use the poke radar if the grass is shiny rusling its shiny i caught like 10 shiny Pokemon and i got dialga shiny
The Red Gyarados is a standard pokémon you'll encounter in HeartGold/SoulSilver, but not in Diamond. In Diamond it's a 'normal' shiny pokémon, which means that you need to be very lucky to catch one. You can find Gyarados at many places in Diamond, but the chance of getting a shiny pokémon is 0.0122%.
