The order comes just a day after Ramos became the first person known to have attracted the virus outside West Africa.
Ramos’ husband, Javier Limon Romero, who is also in isolation, posted photos of their dog, Excalibur, to the Facebook page of Villa Pepa Protective Association, an animal rights organization.
In the post, Romero criticized the decision.
He also asked health officials to consider placing Excalibur in quarantine.
It is still unclear whether the Ebola virus can pass from dogs to humans.
Tom Frieden, the director of the Centers for Disease Control and Prevention, said Tuesday that there is one study which suggests dogs get get Ebola.
“Whether that was an accurate test and whether that was relevant we do not know,” Frieden said.
