totally. thats what I started doing. I was practicing on hill giants and it turns out that dooming + boil blood + scourge is 100 hp over half damage. pulling the pet off at the end till the dots wear off is the key.
this link here that I found on morsakin's post shows the hp for all the mobs.

After some looking its not that big of a pain to out damage the pet.
