| Spoiler: Immediately after the cutscene pause and quick-save. Drink "tawny" potion for the energy regeneration. If given a chance, drink "swallow" as well. Concentrate on the Beast. When it's defeated, all other dogs will die.
Hit it with your Aard sign - that's your best, and probably the only chance. If you have it fully upgraded (all bronze slots filled), it is not that hard. Use the strong style.
As soon as it is defeated, save again.
Yes, it is annoying.
