Plain-English summary
A group of dogs experiencing unexplained diarrhea was tested for a new virus called cachavirus, which was found in about 4% of the samples from dogs with diarrhea. The study involved analyzing feces from both healthy dogs and those with diarrhea, revealing that the virus was present in a small percentage of healthy dogs as well. However, none of the dogs with bloody diarrhea tested positive for this virus. The exact effects of cachavirus on dogs are still unclear, and further research is needed to understand its impact on canine health.

Abstract
Feces from dogs in an unexplained outbreak of diarrhea were analyzed by viral metagenomics revealing the genome of a novel parvovirus. The parvovirus was named cachavirus and was classified within the proposedgenus. Using PCR, cachavirus DNA was detected in two of nine tested dogs from that outbreak. In order to begin to elucidate the clinical impact of this virus, 2,053 canine fecal samples were screened using real-time PCR. Stool samples from 203 healthy dogs were positive for cachavirus DNA at a rate of 1.47%, while 802 diarrhea samples collected in 2017 and 964 samples collected in 2018 were positive at rates of 4.0% and 4.66% frequencies, respectively (healthy versus 2017-2018 combined diarrhea-value of 0.05). None of 83 bloody diarrhea samples tested positive. Viral loads were generally low with average real-time PCR Ct values of 36 in all three positive groups. The species tropism and pathogenicity of cachavirus, the first chapparvovirus reported in feces of a placental carnivore, remains to be fully determined.
