I agree. There are many people who are extremely allergic to any kind of chemicals. A professional Pest Control company has a list and cannot spray anything near these people, who register with the state.
As far as your dogs, they should be kept off the weeds until the chemical has dried and then it is supposedly safe. However, once the dew gets on the weeds, it can potentially be a problem for the dogs, especially if they are sensitive to chemicals. My DH sprayed round up outside once and several days later our cat sneaked out, got on the damp grass and got sick. He had a chemical reaction and had to be treated at the vet. He was sensitive to chemicals even though it had been on quite a while and had dried well. It got wet from the morning dew....
Notify the campground management.
