9. Your dog looks healthy but he vomits often and his stools are often soft

If the animal is fit and properly wormed, then it is a maldigestion, probably related to an intolerance or a food allergy.

The goal of good food is to not have vomiting (1 to 2 times per month maximum), stools very hard and well molded, and no or little smelly gas.

As long as this goal is not achieved, it must be said that the food is not suitable and ask for food advice to his veterinarian.
