Entei, Suicune, and Raikou are not available in Pokemon Emerald, Ruby or Sapphire. They can be brought into the game by trading.
use a articuno and use his attack ice heal and ice thrower
You cannot get the Legendary Dogs (or Beasts such as Raikou, Suicune and Entei) in Ruby without either trading for them or cheating for them because they are not available in the wild in Ruby in any way, shape or form. But you can catch it in Pokemon Ruby Destiny-Reign of Legends. But in the original Ruby or Sapphire you can't get it.
No you cannot catch Entei in Pokemon Emerald.
You cant get entei in any of the hoen region games. Entei is a Johto region Pokemon

You cannot catch/see 'Entei' in Pokemon Ruby. The only way to get it to Ruby is to trade it from Leaf Greean, Fire Red or Colosseum.
You must transfer it from your Pokemon emerald, ruby or sapphire with Pal Park
You can't.

By the way, they are the legendary cats, not dogs. The Pokemon Company revealed that Raikou is a tiger, Entei is a lion, and Suicune is a cheetah.
Well it depends on who you wish to defeat... Try them both on all sorts of Pokemon and see which is stronger for yourself... Remember different Pokemon suit different people. (But I'd say train your Entei ;))
you can only get entei if you chose your starter Pokemon to be baulba saur if you chose squirtal you get rakio and if you chose charmander you get suicune to get your "puppy starter" you have to beat the elite four, get the national dex by having 60 Pokemon ,then get the ruby on island 1, then get the ruby on like island 5,then beat the elite four rematch then randomly you can get your puppy starter hope this helps.....
Entei can only be found in firered and leafgreen if you picked bulbusaur as your starter Pokemon at the beginning of the game and have the national dex and have delivered the ruby and sapphire to celio, then you can find it anywhere around kanto personally it sticks around route 1 you will find it easily there then throw your masterball at it. You can also get an entei from Pokemon colosseum after purifying it.
