Yes, but the damn dogs attack you regardless, so you may as well collect the bodies and make the stew. Besides, as I recall this also gives you XP.
I guess if you really wanted to avoid killing the dogs you could have your rangers and/or druids cast "charm animal," but otherwise those hounds are programmed to attack.
All that being said, I was rarely able to find all the dog meat, and consequently discovered that a couple of shots of "Holy Smite" is also very effective against the umberhulks
