Better to use the earth pet, depends if you mal before the pet roots, always watch for the msg that says its stuck in the ground then begin to resummon the new pet. Go away a split second before the spell finishes up. You'll get better at keeping the mob rooted during resummons.
My fav is to use a monk to pull to me once it's time to resummon the monk call grab agro if he needs to till the new pet gets it back monk fd..
Thats a method you could use the focus item to reclaim energy and keep chain petting all day. Clerics help now to
