Help with a character's pet.

[Magician]

I'm looking for help in regards to a character's pet. Here's what I want to do:

1) Target a player and get his pet's health.
2) Target the pet and heal it if his health is less than a specified percent.

or (kind of the same thing)

1) Get target player's pet's name and set it to a $x (or whatever).
2) /target $x.

Whatever I'm trying isn't working and any help would be appreciated. Thanks. =)
