WHAT IS IT ABOUT?
The central idea of the build is as follows:
Proc a maximum of effects, and in the meantime inflict a maximum of damage.
This will translate to : "Spam Acid Cloud (or Rain of Toads), sacrifice the dogs to refill my mana, re-spawn the dogs, start over."
The most impressive result, is to be able to deal solo with a uber boss (tested without problem in mp6) rendering him harmless (perma-freeze/stun), while the rest of the band deal with the other one.

HOW DOES IT WORK
The WD's skills that activate/trigger (proc) effects the most are acid rain with rune 'Slow burn' or 'acid rain', as well as Plague of toads with 'Rain of Toad'.
The Rain of Toads has the advantage to cost less mana (12) than our natural regeneration (45/s). The acid cloud over powers the proc rate of the toads, but empty our mana pool in 4 to 5 casts.
Once the mana pool is empty, we need to refill it. For this purpose we have the sacrifice with the rune 'Pride'. However, sacrifice the dogs every 45 seconds won't help us a lot.
It's possible to generate dogs with the passive skill 'Circle of life' but that suppose deaths among foes, which is not certain at all, especially against elites.
That's actually the goal of a build based on increased pickup range and the passive 'Grave Injustice', which sees it's limits when climbing the mp levels
Thus, the best way to be sure to have dogs to sacrifice, is to lower the CD (cooldown) of the dogs in order to re-spawn them as fast as possible so that we may sacrifice them more often.
The more our gear evolves and the CD of dogs approaches 0, the more we may abandon Rain of Toads for Acid rain.
Conclusion: the most important element of our gear is the homunculus mojo ( http://eu.battle.net/d3/en/item/homunculus ) which is the core of any C4Dogs build. Combined with the passive 'Tribal rites', together they remove up to 31s of dogs CD.
So, we'll spend our time proc effects. Let's favor freeze and stun, which both render harmless for a few seconds a foe, as well as cancel any action of his.
Freeze is on the belt, stun on the gloves (max 5%). It's possible to get a lot more freeze on the legendary sword azurewrath ( http://eu.battle.net/d3/en/item/azurewrath ) as well as on any weapon or mojo but at a maximum of 2.5% for a one handed (or mojo) and 5% on a 2 handed (freeze or stun). Yet I do not advise to use azurewrath or azkaranth ( http://eu.battle.net/d3/en/item/the-star-of-azkaranth ) due to the dps drop. Still, it's useful to have them somewhere in your backpack if you need it against a boss.
Chill and slow (which have the same effect) are found on shoulders and pants. But are much less valuable than stun/freeze.
Knockback (which is yet to be more extensively tested, and should have an action cancel effect) is to be found on legendary bracers strongarm ( http://eu.battle.net/d3/en/item/strongarm-bracers ).
Blind... That I don't know :p .
Among the most important affixes, we have LoH (Life on Hit). It's to be found on weapon, rings, amulet, and legendary BlackThornes pants ( http://eu.battle.net/d3/en/item/blackthornes-jousting-mail )
With just 1k total of LoH on weapon and amulet, we get more than 3k life per second from stacking acid cloud.
This might turn you into a true tank, and assuming this role (fully or as support of a barbarian or monk) will earn you gratitude in multiplayer games.
We should mention bleed. They are useful against low level mobs, but as soon as you get to mp1, the dps gets negligible.
For the target build (see below), picking up health globes left by your dogs from a distance to trigger Gruesome Feast is a must. Aim for a small 20 yards radius.
This is not mandatory, but since you'll be generating a lot of health globes, a single piece of gear with +10k life on globes/potions will be tremendous. It'll boost your survivability, and allow you to behave 'For the master' style more often, spamming at cqc sacrifice without using the acid cloud.
There are two versions of this build, depending on the budget:
The target build, with a Zombie Dogs (ZD) CD equal or less than 3s: http://eu.battle.net/d3/en/calculator/witch-doctor#RdYiUV!Yhd!bYZZcb
The intermediate build with a CD under 9s : http://eu.battle.net/d3/en/calculator/witch-doctor#RWYVUT!adh!bbZbcZ
Here is as well a variation of the target build, special uber boss : http://eu.battle.net/d3/en/calculator/witch-doctor#RXYTUV!Yhd!bYZZcb
PvP build :
Beware, the lack of 'Pride' rune in the PvP build will make you be very careful on your mana use.
Speed farming build (low MP):
The rune 'lob blob bomb' is interesting, since it stacks 3 blobs that hunt the foes, but does not stack damage nor proc! Blobs only increase the AoE (Area of Effect) of the damage and proc. The other runes are less useful because they proc less or cannot be cast at range.
For exemple 'leeching beast' is nice. 'Life link' was (edit) being bugged (the dogs lacked 'forced armor' from 1.0.4 with this rune, but it's been fixed). The 10% life redirected to them is great, but be careful not to kill them because of that: it gets troublesome to sacrifice dead dogs...
Warning, if you take out 'Final gift', your allies will dislike that choice in multiplayer! Not only does it provide health, but often they've got skills that relate to globes and buff them!
In uber boss mode, the garg is used to provide a hit spot to the uber (when it's not frozen), and allows you to direct the way of the uber's movements in order to take him away from his friend.
