I've been charming frogs in PoS but never in classic so I cant advise you where to go to but this is how it works.

Find an animal and snare it. Always keep your charmed mob snared as you dont want to have a beefed, angry monster running towards at full speed you when charm breaks. Always re-snare at charm break! Pull him to a safe area where you set up your camp. Charm it and put it on guard. Next, buff it with STR and a DS. This will give it an edge against the mob it will be killing.

Now you can go ahead and pull another mob. Get it back to your camp, root it and sic the charmed mob on it. Throw a DoT, gain some distance to have time to react in case charm breaks. As someone has said, you'll need to make damage to get full exp.

I'd advise you to keep the non-charmed mob rooted so you'll have to deal only with your ex-pet should charm break but thats not necessary if you find it to be a mana drain.

As your pet kills the mob its been fighting your next move depends on how many HP it's got left. As you had it buffed up before pulling the other, it should have enough HP to be able to take on another without dying. In that case pull the next mob, have you your pet kill it.

Should your pet have only little HP left, break charm using either invis or hide and take it out. At best, it'll have about 5% left and will be an easy kill but still grant full exp. Whatever happens, you dont want your pet to die to the other mob as you'd lose out on easy exp.

So to sum it up:
1. Get a mob, snare, charm, buff; resnare on charm break!
2. Get another for your pet to fight, root, DoT
3. Break charm, finish off your ex-pet
4. Profit!

It takes some training to be able to pull it off smoothly but its definitly more fun than your usual root/rot. You can play around with pet buffs to see which works best, giving your pet the necessary edge. You'll might even throw a small heal now and then to make sure it survives the fight.
