Where can you find the legendary dogs in Pokemon Leaf Green?

Well actually you can get the legendary dogs in the GBA LeafGreen/FireRed. All you have have to do is find which your strater is

Rakiou-Squirtle

Entei-Charzard (Not Sure)

Suicune-Bulbaser (Not Sure)

--Maybe swich Entei-Charzard and Suicune-Bulbaser Im not sure which gets who but Squirtle get Raikou

Depending one your strter you will only find one of them. I have found aa legendary dog once but its hard to catch. It's very hard to track because you will find it at random. Once you do look into your Pokedex to see its data and track it down. It's very hard and I gave up on tracking Raikou. So you have to beat the Elite Four and Find them at random. Only one of them will appear. I found Raikou 4 times but I fogot to use a pokemon with shadow tag or Mean Look. (Dogs are lvl 50)

Good Luck! =D

Unfortunately, you can't get the legendary dogs in leafgreen or firered. you can only get the 3 legendary birds(zapdos moltres and articuno) and mew and mewtwo. you can get the dogs in ruby, sapphire and i think emerald=(
