Digestive Symptoms of Distemper: Gastrointestinal Impact and Dehydration

Digestive symptoms of distemper include vomiting (30.9%) and diarrhea (43.63-57%), emerging on days 7-14 post-infection due to epithelial infection via nectin-4 and mutations in the H protein (e.g., V478E/L479R), causing malabsorption and dehydration (5-10% body weight loss within 48h). Rare complications: hemorrhagic enteritis (10-15%, 60-70% mortality) and fecal shedding for up to 4 months. Early intervention reduces severity; support your puppy with a stress-free environment and rehydration for a better recovery.
