Arbie melee dog
 Arbites Build - Warhammer 40k: Darktide 

Ping enemies horizontally or vertically to get most use out of dog since now the bolt pistol tech is gone

So example will be

(Ping1/2elite) (horde elites/trash) (ping1/2elite)

1/2 1st or 2nd 

So the dog will jump from left to right or right to left spreading 8 stack of bleed

Other way is

(Ping1/2elite)

Horde elites/trash

(Ping1/2elite)

Just keep in mind this will be harder and you prefer to pong the furthest elite away then ping the closses, since closses would generally eat up your pings when they are on your face

can ignore above tbh since dog doesnt deal alot of bleed anymore but still good cc tool.

NOTE MUST DO FOR BLEED DMG
~~Shoot bolt pistol at bosses to stack bleed as highest you can 4 being max, let dog maintain the bleed stack. ~~

NEW PATCH MADE IT SO DOG BLEED CANT BE MAINTAIN BY DOG, SHOOT 4x tag dog and shoot once in a while to keep stack up, or get rid of razor jaw for target Neutralised

Combo pa heavy heavy loop (can do 1 more heavy if you want) 
heavy light loop single target
need to push and go to single target, do pa light light light (heavy light loop) [might be one less light i dont really remember]

also grenade dog benefits from your ult same as bleed
