Dog parvovirus (CPV) is a highly contagious viral disease that primarily affects puppies, though unvaccinated adult dogs can also contract it. The symptoms of parvovirus can appear suddenly and may include:

1. **Severe Vomiting**: Dogs may vomit multiple times a day, which can lead to dehydration.

2. **Diarrhea**: Often, the diarrhea is severe and may contain blood, which can be a sign of intestinal damage.

3. **Lethargy**: Infected dogs may show a lack of energy and be less active than usual.

4. **Loss of Appetite**: Affected dogs often refuse to eat or drink.

5. **Fever**: Dogs may develop a high fever as their body fights the virus.

6. **Abdominal Pain**: You may notice your dog whining or showing signs of discomfort when their abdomen is touched.

7. **Dehydration**: Due to vomiting and diarrhea, dogs can quickly become dehydrated, which is a serious condition.

If you observe any of these symptoms in your dog, especially if they are a puppy or have not been vaccinated, it is crucial to seek veterinary care immediately. Early intervention can significantly improve the chances of recovery. Keeping your dog up to date on vaccinations is the best prevention against parvovirus.
