Parvovirus is a serious and potentially deadly disease that is highly infectious. Symptoms can be difficult to recognize because parvo can take on different forms in different dogs. At the highest risk for contracting the virus are puppies and any dogs that are kept in unsanitary conditions where the virus can spread through direct contact with another dog or through exposure to dirty living conditions. Early diagnosis is key for successful treatment, and it may mean the difference between life and death for the dog.
Instructions
Learn what is normal. Changes in mood, temperament and routine can be some of the earliest signs that the puppy isn't feeling well. Successfully recovering from parvo depends on early diagnosis, so don't be afraid to contact the veterinarian with concerns.
Take note of any digestive issues. While it's not uncommon for a puppy to vomit or develop diarrhea for a day, repeated episodes can be cause for concern ̵2; especially if the two conditions occur at the same time. Diarrhea can be severe, and is of particular concern if it is also bloody.
Check the puppy's gums and mouth. If the soft tissue of the mouth and gums looks red and inflamed, it can be a sign of the viral infection.
Check for dehydration. Severe diarrhea is often accompanied by dehydration, which can become a serious health issue for puppies as well as older dogs. Feel the puppy's skin. If it feels tight and taut to its body, it may be suffering from dehydration. This is one of the other symptoms of parvo, and can be made worse by the diarrhea and vomiting.
Check your puppy's heart rate. Place your hand on the puppy's side underneath one of its front legs. You should be able to feel its heartbeat; dogs with parvo commonly have a racing heartbeat that is continuously fast during repeated checks. Some dogs are excitable than others, so check it while the puppy is resting for a better indication of whether or not it is a normal heart rate.
Gently press your fingers against the puppy's abdomen. Parvo often results in soreness in the abdomen area; this can be caused by the disease and aggravated by the diarrhea. Often, puppies with parvo refuse food because of the discomfort they are in.
