She can still be remove from the hotel (not sure if she is still there) even if it is a service animal the ADA states this -

Q27. What does under control mean?  Do service animals have to be on a leash?  Do they have to be quiet and not bark?

A. The ADA requires that service animals be under the control of the handler at all times. In most instances, the handler will be the individual with a disability or a third party who accompanies the individual with a disability...... Under control also means that a service animal should not be allowed to bark repeatedly in a lecture hall, theater, library, or other quiet place. However, if a dog barks just once, or barks because someone has provoked it, this would not mean that the dog is out of control.

Q28. What can my staff do when a service animal is being disruptive?

A. If a service animal is out of control and the handler does not take effective action to control it, staff may request that the animal be removed from the premises.

Q29. Are hotel guests allowed to leave their service animals in their hotel room when they leave the hotel?

A. No, the dog must be under the handler's control at all times.
