I recommend pet pvp dabblers visit Discodoggy's blog..it's a winner with insights and fun posts/vids..always current too
My team suggestion for you:
as a third- you have options- junglebeak-p/p or dread hatchling-for big hits- or a gilnean raven (p/s or s/s if you have one)
if you fear the FoAnger, go with a frostfur rat-h/p..p/p ...or even an h/h is viable
The reality is that Graves hammers humanoids..even backlined ones...the Fragment of anger is pretty popular now for the pain it causes the mpd... and it also maims fliers ...Thus, it is a shade riskier nowadays to run fliers and humanoids.
For a long while, undead have overrun pet pvp..you see a fair #of mechs (mpdragonling esp) and elementals
The second tier of 'pvp pet frequency' has fliers/dragons/humanoids/beasts..and aquatic all fairly equal in # in my experience
What you see less of are critters and esp. magic
