Yes, you can get Mew in Pokémon HeartGold or SoulSilver without My Pokémon Ranch but the only two options would have bee via a special Mystery Gift distribution and as of November 24, 2013, there are no distributions for it going on and trading for a Mew.
you can't but if you have a wii there is a wii app Pokemon ranch that is avalible for about 1,500 points (15$) if you get max ranch on that app mew should appear
can get a mew on the ranch, but mew is the 1000nth Pokemon. you get it when you have 999 Pokemon on the ranch.
You can't, you must trade from Emerald (which had an event to get to Mew), or trade from Pokemon Ranch (if you unlocked it).
If you get my pokemon ranch on the wii then transfer 999 pokemon onto it, hayley will give you a mew as the pokemon she brings to the ranch on that day. The pokemon ranch can also be used for an extra storage system for pokemon but only works with diamond and pearl.
If your referring to releasing them in Pokemon ranch, then you can always bring them back.
To get a Mew in Pokemon Heartgold, you could do it through a Nintendo Wi-Fi event.
Unfortunately, there is no way to get Mew without receiving it from an official event or by using a Gameshark or Action Replay. There is however one alternative, if you own Pokemon Ranch for the Wii and a Fourth Generation Pokemon game. When you expand your ranch to level 25 by depositing 999 Pokemon in the ranch, Hayley will ask for a Pokemon egg for her Mew. Just trade her an egg and you'll have a Mew.
If you have log cabin ranch then you can receive Mew from Hayley(only pearl/diamond)
You can never get Mew without hacking or getting it from a hacking friend. Besides, its Mew and Mew2 O_O
Deposit 999 Pokemon into the ranch from pearl or diamond.
Mew cannot be caught in the wild without using an Action Replay. Legitimately, you can obtain a Mew from Hailey on the Pokemon Ranch if you have acquired 999 Pokemon or trading for it from a nearby friend.
