Ebola Pooch Excalibur Pictured on Doggy Death Row

Excalibur, the dog of the Spanish nurse infected with Ebola, barks from a balcony in Madrid, Spain, Wednesday, Oct. 8, 2014. Three more people were placed under quarantine for Ebola at a Madrid hospital where a Spanish nurse became infected, authorities said Thursday. More than 50 other possible contacts were being monitored. The nurse, who had cared for a Spanish priest who died of Ebola, was the first case of Ebola being transmitted outside of West Africa, where a months-long outbreak has killed at least 3,500 people and infected at least twice as many.

The dog belonging to a Spanish nurse infected with Ebola was seen barking on the balcony of an apartment in Madrid on Wednesday as dozens of animal lovers staged a protest aimed at saving the condemned pooch.

Authorities announced they would euthanize Excalibur to prevent the spread of the virus after his owner Teresa Romero Ramos became the first person infected outside of West Africa. Ramos' husband, who is also in isolation, said he had left Excalibur alone at their apartment with food and water and appealed for the public's help in saving the dog's life. An emergency veterinary services vehicle was seen parked outside the entrance of the apartment building on Wednesday.

Owner Javier Limon said he had left the dog alone with a bathtub full of water and 33 pounds of dog food. “The door to the terrace is open so he can do his business. The animal is OK at home alone,” he said. SUSANA VERA / Reuters
