Resumen

The global presence of SARS-CoV-2 in household pets is acknowledged, yet documentation remains scarce, leaving many regions unexplored. Thus, our study sought to fill this gap by investigating SARS-CoV-2 presence in dogs visiting veterinary clinics during the third pandemic peak in eastern Colombia. We collected and analyzed 43 oropharyngeal and rectal swabs using real-time PCR assays targeting the Envelope Gene of SARS-CoV-2. Out of these, two dogs tested positive, indicating an infection rate of 4.7%. Further examination through complete sequencing and phylogenetic analysis revealed the lineage B.1.621 for the SARS-CoV-2 genome. Consequently, our study unveils the first documented cases of Canis lupus familiaris infected with the Mu variant of SARS‐CoV‐2, the variant with the most death burden during the whole pandemic in Colombia. Remarkably, these cases presented mild and reversible respiratory and gastrointestinal symptoms, or no clinical manifestations at all. This sheds light on the virus's interaction with our four-legged companions, offering valuable insights into its transmission dynamics and potential effects on animal health.
