There should be a way to resurrect your pet or at least let it self heal. I cannot tell you how disappointed I was that all my planning and work (taming the wolf) went up in smoke within minutes.

That's working as intended that you learn the strengths/weaknesses of mobs vs tames.

If you had been more conservative, you'd've moved the fresh tame safely to a breeding pen. Going near a swamp typically isn't considered a safe route.

Also wolves are pretty weak against damage over time like poison fire etc and aoe attacks(when you've a bunched pack of wolves that'll take down the pack fast).

All in all this was a survival learning experience really not a fault of the game's design implementation.
