Please don't tell me the strategy is something silly like going full tank DH and kiting between Aid Station Sentries with Brooding, that is just silly. Also, I know of several interesting tactics but they don't work very effectively:
Spike Trap - Sticky Trap the dogs -> Fan of Knives. Doesn't work when the dogs have so much EHP they survive critical Fan of Knives and the WD can just dismiss the dogs and resummon them. Also, the AoE range is rather limited with a running WD.
Spike Trap - Echoing Blast with Caltrops - Torturous Ground. Requires legacy Natalya's with MASSIVE discipline, the idea is to vault into the WD, spam Smokescreen, Caltrops, and Spike Traps to keep the WD snared. Doesn't work if the WD is so tanky the DH runs out of discipline before that occurs. Furthermore, it leaves the DH open with no discipline, also the 0.5 second windows between Smokescreens can get the DH into serious trouble with Fire Bats and Spirit Barrage.
