More: Duncan was rescued on June 6th and on June 8th he was admitted to the animal hospital with parvovirus. He stayed hospitalized for 11 days and finally overcame the virus. Throughout his fight, 4 of his siblings passed from parvo. He lost over 40 percent of his bodyweight and was released at just 8 pounds. Today, he is a healthy 60 pound puppy with a ton of energy. He still has some lingering affects of parvo, and is still on medication...but I will do what it takes to get my boy at 100 percent.
