hey so first suggestion take a look at the WD build thread http://us.battle.net/d3/en/forum/topic/7350275486
Second the top builds would be:
1. a zombie bear build using Vision Quest as your mana regen passive with corpse spider(widow maker rune). these two skills will make it so you can spam bears and not run out of mana.
2. spirit barrage(well of souls rune) and rush of essence and blood ritual as your primary mana regen skill the in addition to zombie bears or acid cloud or both
3. Rain of toads/acid rain build (dont know much about this one though)
4. 0 second dog but that is gear dependent
For your additional skill slots use what you like but i would recommend spirit walk for your escape skill/avoid reflect damage skill.
Also your dogs scale off of your hp and allresist and armour, but depending on what mp your are playing your dogs can die pretty quick. i only really see them surviving when i use fierce loyalty and a with my life regen they usually never die.
I hope that helps!
PS gear looks pretty solid
