Recognizing the signs of Canine Parvovirus (CPV) is crucial for early detection and prompt treatment. CPV is a highly contagious viral infection that primarily affects puppies and unvaccinated dogs. It can be life-threatening if not identified and treated promptly.

There are several key signs to watch out for when it comes to CPV:

1. Gastrointestinal Symptoms: CPV attacks the lining of the intestines, leading to severe gastrointestinal symptoms. These may include vomiting, diarrhea (often bloody), loss of appetite, and abdominal pain. The diarrhea may have a distinct foul odor.
2. Lethargy and Weakness: Infected dogs often appear weak and lethargic. They may have a lack of energy, reduced interest in activities, and even difficulty standing or walking.
3. Dehydration: Due to severe vomiting and diarrhea, dogs with CPV can quickly become dehydrated. You may notice signs such as sunken eyes, dry gums, and excessive thirst.
4. Fever: A high fever is commonly seen in dogs with CPV. Normal body temperature for dogs is around 101-102.5°F (38.3-39.2°C), so any temperature above this range should be a cause for concern.
5. Depression and Loss of Interest: CPV can also cause depression and a loss of interest in surroundings. Dogs may become less responsive to their owners, show less enthusiasm for playtime, and withdraw from social interactions.

If you notice any of these signs in your dog, it is crucial to seek veterinary attention immediately. Early detection allows for timely treatment, which increases the chances of a successful recovery.
