Is a government canine considered a pet? Service dog?

[Stephanie Amezola]

We have a strict no pet policy and current potential tenant stated during our pre-screening that they do not have pets. However, at the property showing the husband - who works for Homeland Security- has a K-9. He did not state that the canine lives with them, but we also did not ask for clarification. Is a government canine considered a pet? I tried researching what qualifies as a service dog and saw no mention of government canines.
