On Jungle Cruise (which I have ridden countless times with my dog) we had the CM let us know she wouldn't "shoot" the hippos so that my dog wouldn't jump or be frightened. My dog doesn't mind the shots, but she is the first CM to care to realize that it might've scared her.
And now we just had another CM ask us if the gunshots at the Golden Horseshoe would bother our dog.
CM's are on it today! Never had anyone be so accommodating.
