Trust me, it doesn't.
Although it'll still take you months.
I've leveled most of the pets used in the various Tamer daily guides and now I'm not sure what would be the most effective approach to leveling the rest of my 400+ pets. I've raised everything to at least L5 and I'm being careful not to level non-rares past L15, of course.
That's a good start.
You want to do the dailies, then spend an hour or so stone hunting and leveling pets in wild battles.
If you haven't upgraded everything, then you want to do all the bag daily tamers each day. If you have alts you can park at each of the non-Pandaria tamers, that cuts down some time. Then there's the nice loop around Pandaria for the regular and spirit tamers. I wouldn't worry about the BoF since they give crappy exp, unless you don't have all the pandas and/or really want the extra stone chances.
Use the non-Pandaria tamers to bump up your low-level pets. Use Pandaria tamers to level to 25.
Once you have upgraded everything, then it's just Pandaria tamers dailies and wild fights to adjust pet levels.
Assuming you always wear your safari hat, there's certain points for efficient use of the Pandaria tamer XP. Level 10, level 15, level 19, level 21 and level 23.5. Each tamer fight will get you to the next point, and of course, a 23.5 pet will jump to 25 after a single fight. Aim to get your low level pets to one of those targets using the wild fights. You can level a 1 to 10 in 5 or 6 wild fights in Pandaria.
And to toot my own horn, here's a link to a thread. viewtopic.php?f=3&t=3871
