Adding to what was said above, Using the Spiky bear with Super cures is my personal method.
What I use:
- Strong pet
- Super Cures
- Spiky bear Model
How I do it:
I use the Spiky bear model to attack, it has the most health out of all of the models. It leaves a small amount of health left, giving you a few seconds to heal yourself. I suggest attacking him, then switching to F1, with your Super Cures ready for when you are hurt, then simply click.
The alternative method, as stated above, is roaring from up high. I personally dislike this method, as you have to buy 250 roars, or 200, to make sure you have enough, and it takes a while + uses more coins, if you're buying it from the "Skills" NPC, Located int he Bazaar.
