A dog in New York has become the first documented case of an H1N1 virus-infected dog in the United States. The test was performed by Idexx Laboratories, and results were confirmed by Iowa State Laboratories, according to an American Veterinary Medical Association (AVMA) news release.

The 13-year-old neutered male mixed breed dog was tested for the virus after his owner took him to an emergency clinic in Bedford Hills, N.Y. The dog had a dry cough and a fever, and the owner reported that the dog was lethargic and not eating. The owner had also tested positive for H1N1 earlier in the week, according to the Idexx case report.

The report says that thoracic radiographs indicated “evidence of pneumonia with consolidation of the right cranial and middle lung lobes and prominent air bronchograms.” A PCR test for H1N1 came back positive, while tests for other pathogens including canine influenza H3N8 came back negative.

The dog was hospitalized and treated with intravenous fluids, antibiotics, and received saline nebulization and coupage four times a day. After 48 hours of supportive care in hospital the dog improved and was released.

According to the Idexx report, the dog is doing well at home and is scheduled for a follow-up visit and radiographs.

Earlier this month, China reported two positive cases of H1N1 virus in dogs, but the AVMA has not confirmed those results.
