no.it depends on your 'starter' pokemon,not if you caught all of the other starters or got them in trades. 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.
In Pokemon Leafgreen or Firered, you should try and catch the one last legendary Pokemon with your master ball if you saved it. (It depends on your starter Pokemon on what legendary you can get.)
No you can catch one of the legendary dogs anywhere in kanto, wich one you will find depends on the weakness of your starter pokemon
You can only catch one of the dogs which depends on what starter you chose to get the rest get one from firered to get the second and the third from Pokemon colosseum.
try to catch your legendary. It varies on which legendary depending on what starter you chose.
There are 7 catchable rare Pokemon in leafgreen however here's the catch, there are 7 but you can only catch one of 3 legendary dogs Raikou/Suicune/Entei it depends on what starter Pokemon you chose. Also there are 3 event only Pokemon you can get making the total to actually 10 in all.
you have to catch it in firered or leafgreen and transfer it to the pal park via the dual slot
mewtow zapdos moltres articuno mew entei raikou suicune
You can not catch a Charmander in Pokemon Firered you must ether choose it as your starter or trade one from Leafgreen
If you have the starter Squirtle, you will find Rakio in the wild after beating the Pokemon League.
1. Mewtwo, if you catch him in the Cerulean Cave, he will be at Level 70!!!
You cannot catch Registeel in Pokemon LeafGreen. This is due to FireRed and LeafGreen being able to trade with Ruby and Sapphire. Pokemon Ruby and Sapphire have the three legendary golem Pokemon including Registeel.
You dont :) you gotta trade it if you didnt choose it as your starter
