There’s no rule that says dead creatures can’t take action. You’ll usually become Unconscious first, but instant death effects including massive damage bypass that. So you can just keep playing.

Dogs aren’t a playable race so they can’t have class levels. But there is no rule saying dogs can’t learn languages. And they can be Sidekicks, but that’s more a rule specifically designed to allow them to play. There’s also no rule saying they can’t wield weapons. One-handed and two-handed weapons both require hands to use, but there aren’t actually any weapons listed as one-handed.

That’s on the same level as disintegrate making you able to play a sentient pile of dust.
