Canine parvovirus (often called “parvo”) is a highly contagious and potentially deadly virus that primarily affects young and unvaccinated dogs. The symptoms can escalate quickly, so early recognition is crucial. Here’s what to watch for:
⚠️ Early Symptoms
- Lethargy: Your dog may seem unusually tired or inactive.
- Loss of appetite: Refusing food or treats.
- Fever: Elevated body temperature, though not always present.
🚨 Progressive Symptoms
- Vomiting: Often persistent and severe.
- Diarrhea: Usually foul-smelling and may contain blood.
- Abdominal pain: Dogs may whimper, hunch over, or resist being touched.
- Dehydration: Due to fluid loss from vomiting and diarrhea.
- Rapid heart rate and breathing difficulties: Especially in puppies.
- Low white blood cell count: Weakens the immune system, making secondary infections more likely.
🐶 In Puppies
- Collapse or weakness
- Hypoglycemia (low blood sugar)
- Hypothermia (low body temperature)
Parvo attacks rapidly dividing cells, especially in the intestinal tract and bone marrow, which is why symptoms are so severe. If you suspect parvo, immediate veterinary care is essential—there’s no specific cure, but supportive treatment can save lives.
