A total of 180 swab samples were collected from dogs with non-clinical symptoms (healthy group) and dogs with abnormal respiratory, digestive, and urinary-reproductive manifestations (ill group) from animal clinics for detecting of circovirus by PCR assay. The results showed that 2/90 (2.2%) of dogs in healthy group were positive with canine circovirus, while 8 of 90 (8.9%) dogs in ill group also were positive with canine circovirus. In the ill dog group, dogs showing diarrhea symptom had the highest rate of detection for canine circovirus (about 16.7%), followed by the dogs showing respiratory and reproductive problems (6.7% and 3.3%, respectively). The results obtained in this study confirmed that canine circovirus was present in healthy and ill dogs in Vietnam.
