Recently I' ve heard that some hunter in WOW can get pets with their original huge size and elite target frame... So i tried for days until i was disappointed to read the following text:

"Recently I’ve been getting a lot of reports about really big hunter pets — pets that are much larger than a tamed pet of their level should be. A lot of people have written in to ask me how they can get a such huge, huge pet.

The short answer is: You can’t.

The long answer is: Sometimes other people will see your pet as huge, but unfortunately it’s not real and it’s not permanent.

So far as I can tell, this is an extension of the glitch that sometimes let’s us see a tamed pet with it’s elite tag (and gold dragon) or rare tag (and silver dragon) still in place. My theory is that the client and server are temporarily out of sync, possibly due to internet lag or slow server performance. The client has received info about the base properties of the pet, which probably includes its model, wild name and the fact that it is elite. But for whatever reason the client didn’t receive the tamed info — like the pet’s new name, or the fact that as a pet it is no longer elite. "

Well all of those are only ai think i have to give up trying, even if  it' s only a little desire of every hunter player T.T

Here is a clip of record of huge pet:
