Auto Furious Howl Macro

What is a macro to make your wolf cast furious howl continuously while standing next to you during a fight?

The only way I’ve seen him do it is if I send him in to attack and then call him back, which engages him in combat first.

My current macro is
/showtooltip Pet Attack
/targetenemy [noexists][dead][help]
/petfollow
/petattack
/cast Hunter’s Mark
/cast Furious Howl
/cast Charge
/cast Dash
/cast Dive

Macro it to Aimed Shot if you want to be lazy.
