To keep a puppy hydrated with parvo feed it real mashed potatoes (real potatoes, not the shit from the box!) and take some white rice (not min. rice) throw it into a cup with some hot water and it should start to cloud up. The cloudy water contains all the vitamins and starches the puppy needs to stay hydrated. Also Chicken Soup broth and Pedilyte every 3 hours work for those not eating. If you czn keep it alive 10 days the dog should live and never get parvo again. Parvo lives in the ground 2 to 7 years. All animal who die of parvo should be creammasted. 3 litter 6 dollar shots can save life
