I. Rotavirus Infection in Puppies

Rotavirus infection is primarily an intestinal infection in puppies. It has diarrhea as its main feature, and adult dogs usually take recessive passage after infection.


Rotavirus is present in the intestinal tract of the affected dog and is excreted in the feces, contaminating the surrounding environment. The digestive tract is the main route of infection for this disease. Healed animals can still detoxify from the feces, but it is not known how long the detoxification lasts. Rotavirus has some cross-infection between humans and animals, so as long as the virus persists in humans or one animal, it may cause long-term transmission of the disease in nature.


It mainly affects puppies born within 1 week, with sudden onset, diarrhea, yellow-green loose stool and mucus, which can last for a week. Severely ill dogs have hemorrhagic enteritis with blood mixed in the stool, rapid heartbeat, and decreased body temperature, which can lead to death.


1. Epidemic characteristics: Dogs of all ages can be infected, but adult dogs are generally recessive and lack obvious symptoms. The disease occurs mostly in the cold season. Poor hygiene can often induce the disease.


2. Clinical features: Puppies often have severe diarrhea with draining to mucus-like stools that can last 8 to 10 days. However, there is no major change in appetite or body temperature.

The initial diagnosis is usually made based on the changes described above. A definitive diagnosis is made by electron microscopy. An enzyme-linked immunoassociation test is also a commonly used diagnostic method today.


1. The sick dog should be immediately isolated to a clean, dry, warm place, stop feeding, and switch to glucose-glycine solution 45 g g glucose, 8. 5 g calcium chloride, 6 g glycine, 0. 5 g citrate, 0. 13 g potassium citrate, 4. 3 g potassium dihydrogen phosphate, 200 ml water or glucose saline and 5% sodium bicarbonate solution to prevent dehydration and desalination.

2. Ensure that the puppy receives sufficient colostrum to give it immune protection. Subcutaneous injection of adult dog serum can also be tried. No vaccine is currently available.
