It depends on the pet family. Also depends on what abilities you have trained him.
Two absolutely fabulous hunter resource sites are:

Take note that there are some specific pets that are basically gimped. They are usually a rare type of that family that happens to have crappy stats or something else weird. Petopia lists most of em to avoid.
