Other animals are an undeniable distraction to service dogs, and there could even be a row between the two animals in a worst-case scenario. For that reason, owners of non-working animals should keep their pups away from service dogs at all times. If this does not happen, the customer who uses a service dog may ask you for help to manage other clients.
It's also important to know that The Americans with Disabilities Act (ADA) guarantees people with disabilities who use service dogs equal access to public places such as restaurants, hospitals, hotels, theaters, shops, and government buildings. So, if any customer complains to you about having a working dog nearby, you can help to elucidate this matter.
