For DPS, use Claw and Bite. Bite has higher TPF (Threat Per Focus) than Claw, but isn't spammable. While soloing, I've found that Bite has a higher prio than Growl, so it slows down my pet's threat gen. I usually turn Bite off and use only Growl and Claw as damage abilities (if I've got a pet who has those two abilities, ofc).
