Umbrellas

I managed to get in touch with the caregiver who successfully drove the dogs off from his area. He mentioned that they decided not to go with the pots and pans because it might be too noisy. He said that he and another two caregivers waited for the dogs for two nights, and then they had a confrontation with the dogs. They used umbrellas and successfully drove them off. He suggested that it is best to have a few people as one person may not be sufficient. The dogs have not been seen since, and this happened a good three to four years ago. I'm asking him for specific instructions and will post them once I hear from him.
