Can dogs get COVID-19, and if so, how susceptible are they compared to humans? What are the typical symptoms in dogs, and are those symptoms generally mild, moderate, or severe? Also, is there any risk of dogs transmitting the virus back to humans or other animals, and what precautions should dog owners take if they suspect their dog has been exposed to or contracted COVID-19? Are there any specific breeds that are more vulnerable?
Answer
Yes, dogs can get COVID-19, also known as SARS-CoV-2.
Evidence and Details:
-
Natural Infections: There have been documented cases of dogs naturally infected with SARS-CoV-2, often after close contact with infected humans. These cases have been confirmed through PCR testing and/or antibody tests.
-
Experimental Infections: Studies involving experimental infections of dogs with SARS-CoV-2 have shown that they can be infected and can shed the virus.
-
Severity of Illness: Generally, dogs infected with COVID-19 tend to experience mild or asymptomatic infections. Some may show symptoms like:
- Fever
- Coughing
- Lethargy
- Sneezing
- Nasal discharge
- Decreased appetite
- Vomiting
- Diarrhea
-
Transmission: While dogs can be infected, their role in transmitting the virus to humans or other animals is considered low. Most infections in dogs are believed to result from transmission from infected humans to the dog. Studies have indicated that viral shedding in dogs is generally less than in humans.
-
Variants: Dogs can be infected with different variants of SARS-CoV-2, similar to humans.
-
Risk Factors: Close contact with infected individuals is the primary risk factor for dogs becoming infected.
-
Testing: PCR tests (nasal or throat swabs) and antibody tests are used to diagnose SARS-CoV-2 infection in dogs.
-
Prevention: If you have COVID-19, minimizing close contact with your dog can help prevent potential transmission. This includes avoiding cuddling, kissing, sharing food, and allowing them to lick your face. Washing your hands frequently is also important.
-
Treatment: Most infected dogs recover without specific treatment. Supportive care, such as ensuring they stay hydrated and comfortable, is usually sufficient. If a dog experiences more severe symptoms, veterinary care is recommended.
- Vaccination: While COVID-19 vaccines for animals have been developed, their use is typically reserved for situations like potential outbreaks in mink farms. The decision to vaccinate a dog against COVID-19 should be made in consultation with a veterinarian, considering the specific risks and benefits.
