A popular Missoula dog park has been closed down for cleaning.
Missoula Parks and Recreation and Missoula Animal Control have closed Montana Rail Link Dog Park after a dog tested positive for parvovirus .
Unvaccinated dogs and puppies under the age of four months are most at risk for the highly contagious virus.
Parks and Recreation plans to clean and disinfect the park's wood chip surface material before the park re-opens sometime next week.
Symptoms of canine parvovirus infection can include severe vomiting, diarrhea, lethargy, and loss of appetite.
Dogs who exhibit these symptoms should be seen by a veterinarian immediately.
