Next time will ask about "pet" policy. Dog in room next door got out of the room when door was left open and attacked my husband as he was returning to our room. Fortunately, he was not injured, but very frightened at having to fight the dog off. Dog owner seemed stunned and was apologetic. We had no idea, prior to the attack, that a dog was housed next door to us. Have to think about whether to stay in "pet friendly" hotels in the future.
