Why are dogs arriving in the US with questionable rabies protection?

When you bring a dog into the country, you trust its paperwork shows it's protected against rabies. But a recent look at import records found something concerning: 132 dogs that arrived in the United States from countries where rabies is common had documentation for rabies vaccines that might not work. The check didn't involve testing the dogs themselves or tracking what happened after they arrived, so we don't know if any were carrying the virus. It simply spotted a potential problem in the system—vaccination records that raised red flags. This is a reminder of how a breakdown in paperwork for a single deadly disease can have serious consequences, even if the full scope of risk here is still unknown.
