Animals love food and when you own a pet, you really need to take care of what sort of food your pet eats. Provide the best nutritious food to your animal like meat, fish, cat or dog biscuit and so on. I have seen so many animal pencil drawing artists that use to sketch animals eating their favorite food. When it comes to domestic dogs they can derive nutrition from vegetables and fruits. Making your animal eat healthy is the requirement for your meat. Make sure you do that.
