If your dog has diagnosed with parvovirus or wanted to know about How Convenia Treats Parvovirus in dogs and cats? Then absolutely you’re at the right place. Because in the following article, I would explain all the myths about using antibiotic injection (Convenia by Pfizer Pharmaceuticals Company) is well known, a life-threatening viral infection of dogs i.e, Parvovirus.

How CONVENIA (Cefovecin Sodium) Injection Treats Parvo in Dogs?

CONVENIA (cefovecin sodium) is an injectable antibiotic that is used to treat a variety of bacterial infections in dogs, including skin infections, urinary tract infections, and respiratory infections. It is not effective against viral infections, such as parvovirus infection (also known as parvo).

Parvo is a highly contagious viral disease that affects dogs and puppies. It is caused by the parvovirus, which attacks the intestinal lining and immune system of infected dogs. Symptoms of parvo include vomiting, diarrhea, loss of appetite, and lethargy. The disease can be severe and can be fatal, especially in young puppies and immunocompromised dogs.

CONVENIA is not a recommended treatment for parvo, as it will not be effective against the virus. Instead, treatment for parvo typically involves supportive care, such as IV fluids to prevent dehydration, medications to control vomiting and diarrhea, and nutrition support. In severe cases, hospitalization may be necessary. If your dog is showing signs of parvo, it is important to contact your veterinarian as soon as possible for proper treatment.

Convenia is the trademark of Pfizer Pharmaceuticals (Pvt) Limited. It is the first and only injectable antibiotic drug that is approved by the FDA (Food and Drug Administration) in the United States of America.

Zoetis Pharmaceuticals is a subsidiary of Pfizer pharmaceuticals Private Limited. Zoetis is well known for his work in providing the best medicines for animals.


It contains an active ingredient Cefovecin Sodium, a highly effective, broad-spectrum cephalosporin (class of antibiotic drugs), which treats a variety of gram-positive and gram-negative bacteria. Cefovecin is specially formulated to treat the skin infections caused by Staphylococcus intermedius and Streptococcus canis in canines.

It also treats a variety of other infectious diseases of the skin, urinary tract, respiratory tract, ear, nose, eyes, nails, and mouth in the canines and felines. 

Let’s get back to the primary question, How Convenia treats Parvo?. Basically, Convenia does not treat parvovirus. Yes, absolutely yes. It’s true. Cefovecin is a strong antibiotic preparation, a single time subcutaneous injection, used to treat just bacteria infections in animals, especially in pets. It does not kill a virus or treat a viral infection, or infections caused by parasites or molds in the body. 

Why Veterinarian Prescribe Convenia in Parvovirus for Dogs?

Antibiotics do not use to directly kill viruses, but they may use to treat secondary infection caused by the virus in the body. Parvovirus is more likely to attack the digestive area of the body. It wreaks havoc the crypt cells of the intestine, where the present bacteria may enter into the bloodstream and cause more serious, life-threatening problems like septicemia.

So, a veterinarian suggests antibiotic treatment, more often an antibiotic to treat any secondary infection caused by a virus in the body. Cefovecin Sodium injection is more likely suggested because the oral antibiotic treatment does not give better results. It may due to poor antibiotic absorption in the gastrointestinal tract or less acceptance by the dog.

Convenia Dosage for Dogs with Parvo


This antibiotic veterinary drug reconstituted in 10ml sterilized water. It should be refrigerated in between 2-8 degrees centigrade temperature after reconstituted and may be used for 56 days after reconstitution. After reconstituted 10ml vial contains 800mg cefovecin sodium. So, the 01 ml solution contains 80mg cefovecin.

The recommended dose of cefovecin sodium for canines is 3.6mg/lb or 8mg/kg. So, for a 10lb dog 0.45ml cefovecin sodium is the ideal dose after reconstitution. Your Vet may determine the exact amount of dose after diagnosing the severity of the infection and observing the condition.

Convenia Injection Administration in Pets

This product is not suitable for dogs below 4 months of age. A single dose of Convenia injection administered subcutaneously (below the skin and above the muscles). There is no need for a second dose within the first 14 days of the former administration.
