You can do it through the UI. I'm not in game now but the icon is there. Try using the advanced options. You can either release tiers of pets, a single pet or all pets.
The command is something like /release_all_pets I think if you want to macro it.
Type /cmdlist and you'll see it.
Either way you don't have to do one at a time.
/petcomall dismiss
total kick to the gut
This is like having Ra's Al Ghul show up at your birthday party.
/releasepets also works.

I usually hot key this for convenience:
/bind control+F12 petcomall dismiss
if I managed to spell that all correctly.
Like the title says is there a Macro I could use to dismiss all my pets at once?..tired of clicking dismiss on each one. Would make my life much easier if there is. Thx in advance.
