just use a dropper and put pedialyte and activated charcoal down his throat until he feels better. Do it every hour or half hour at 1/2 tsp of charcoal to 1/2 cup of pedialyte with some beef or chicken broth in it. Only give the charcoal pedialyte every 3 hours. This of course is 24/7. I have had 2 pups with parvo and both survived with this method. To get his blood sugar up after he stops vomiting and stops his diarrhea put white corn syrup on his gums to get him to want to eat and I put lard in a syringe and put that on his tongue.
