This invention discloses a method for preparing pet stem cell exosomes, belonging to the field of animal medicine technology. This invention treats stem cells with an inducing agent to secrete exosomes with high TFR expression on their surface. These exosomes specifically target the conserved region of the NS1 gene, a non-structural protein of the parvovirus family, allowing the internally loaded siRNA and trefoil factor 3 to target and enter infected cells, directly inhibiting viral replication at the gene level to treat feline panleukopenia virus (FPV) and canine parvovirus infections and alleviate sequelae. This invention solves the problems of existing technologies, such as difficulty in targeting, lack of specific drugs, reliance on intensive supportive care leading to a short treatment window, inability to directly clear the virus, risk of cross-infection, and potential long-term sequelae. It has the potential to be applied to the preparation of drugs for treating canine parvovirus and feline panleukopenia.
