When an animal charges, dodge in the direction opposite of where they are attacking. Some creatures have tells that will give you a hint as to how to avoid their attack. For example, a bear raising its left paw will follow up by swiping down and towards its right.
Boosts
Save your Boosts until absolutely necessary. Instead of spending gold to purchase Boosts, use it to buy weapons. After using the X-Ray boost, try to remember where the heart and lungs were located. If you encounter the same type of animal again, you will now know where to aim without another Boost.
