I'd drop Weight of the Lex and pick up Soulguilt Scans since strength bonuses are multiplicative to other sources of bonus damage. Running dog without bleed pounce is passing up a decent amount of free damage even after the fix+nerf, so consider swapping Hammer of Judgement to No Escape and grabbing Razor Jaws. You should also consider swapping auras to the dog coherency +DR one and picking up Imposing Force. Concussive is fairly redundant if you're running with one of the Arbites weaps, and dropping it frees up a point. Leave True Grit in if you want, but if you feel inclined to drop it, then consider Engage, Canine Morale, Weight of the Lex, or Hammer of Judgement. Also, if this is an Auric build, Target the Weak likely won't change (m)any breakpoints since stuff dies so quickly anyway, but test that yourself. It IS a good source of damage that won't stack additively with all the other normal +damage options in the talent tree, and I do run it in my Havoc builds.

Alternatively, dropping the dog entirely and going all in on LW+Forceful is a strong option. But Arbites has so much damage that you can afford to trade a little bit to turn the dog into an AOE bleed machine that'll help thin out mass.
That said, I don't really bother testing breakpoints as Arby, so if you really want to minmax, you'll have to play around with shit on your own.
