If an ambulance is on its way to save someone, and it runs someone over, does it stop to them?

Yes, another ambulance will need to be dispatched to the other scene because the ambulance cannot leave the scene of the accident until it is finished (treating the person who called).

Your dog can sniff at or even eat a bit of catnip. the herb is edible and not harmful. just don't expect them to roll around like a cat would! your dog may scrutinize catnip by licking and smelling at it, or be totally indifferent to this stimulant.
