If it is just intestinal parasites, several dewormings should be enough to set Nacho on the path to recovery. It may take a week or two unless he has an exceedingly high worm burden. If he isn't showing improvement a few days after being dewormed, have him rechecked by your veterinarian. Supportive care may be indicated until he is feeling better.
