Frequently Asked Questions
What are the most dangerous viruses for dogs?
The most serious include parvovirus, which causes severe, often fatal, bloody diarrhea in puppies, distemper, which attacks multiple body systems, and rabies, which is deadly and can spread to people. Canine hepatitis and, less deadly but very contagious, canine influenza are also important.
Can vaccines prevent dog viruses?
Yes, and this is the key point. Core vaccines protect against parvovirus, distemper, hepatitis and rabies, the most dangerous viral diseases. Keeping vaccinations and boosters up to date is by far the most effective way to protect your dog, especially vulnerable puppies.
How do dogs catch viruses?
It depends on the virus. Many spread through contact with infected dogs or their feces, urine or saliva, and some, like parvo, survive a long time in the environment on surfaces and soil. Others, like rabies, spread through bites. Unvaccinated puppies are the most at risk.
What are the signs of a viral illness in dogs?
Signs vary by virus but often include vomiting and diarrhea, coughing or nasal discharge, fever, lethargy and loss of appetite. Because several serious viruses share these early signs, any young or unvaccinated dog with these symptoms should see a vet promptly.
