If an unvaccinated dog is exposed to a confirmed rabid cougar, what is the appropriate action?

The situation of an unvaccinated dog being exposed to a confirmed rabid animal, such as a cougar, requires adherence to public health guidelines and rabies control measures. In this context, quarantining the dog at animal control for 180 days is appropriate because rabies is a fatal viral disease that can be transmitted to other animals and humans.

This substantial quarantine period allows for monitoring the dog for any signs of rabies infection. During this time, if the dog were to show symptoms, immediate action could be taken to prevent potential spread. It's crucial to ensure that the dog does not have the opportunity to expose other animals or people during this period.

The other options would not sufficiently mitigate the risk associated with rabies exposure. For instance, home quarantines may lack the necessary surveillance and care, especially in the case of a potentially rabid animal’s exposure. Meanwhile, euthanasia is typically reserved for situations where the dog is already symptomatic or when the risk of rabies cannot be effectively managed. Therefore, the choice of a 180-day controlled quarantine best addresses the public health concern regarding rabies exposure in an unvaccinated dog.
