Canine parvovirus is a highly contagious virus that primarily affects dogs, especially puppies. It attacks the gastrointestinal tract, leading to severe vomiting, diarrhea, and dehydration. The virus spreads through direct contact with infected dogs or contaminated surfaces, making it crucial for pet owners to maintain hygiene and vaccination. Vaccination is the most effective way to prevent canine parvovirus. Puppies typically receive a series of vaccines starting at six weeks of age. If a dog is infected, prompt veterinary care is essential, as the disease can be fatal without treatment. Early detection and supportive care can improve recovery chances.
