Parvovirus is a deadly threat to an unvaccinated dog. It is so infectious that anyone or anything can become a parvovirus carrier simply by coming in contact with an infected dog’s feces or even by walking through an area where the feces had once been, which is how the virus is typically spread.
The virus can survive extremes of both hot and cold temperatures for weeks, or even months, so it can remain on the ground long after the actual feces have been removed.
Some of the primary symptoms of parvovirus are vomiting, severe diarrhea, depression, or a sudden, unexplained loss of appetite. If you notice these symptoms in your dog, you should take him to the veterinarian as soon as possible. While there are presently no drugs that will kill the canine parvovirus, there are proven treatments available to control the complications of the disease.
To prevent the spread of parvovirus, follow the immunization protocol recommended by your veterinarian.
If there is a chance that you have walked through an infected area, clean your shoes with a solution of one part liquid household bleach to 30 parts of water to help minimize the virus’ spread.
