We have a filter on the cold water of our kitchen sink. We always just fill the dog jug with the filtered tap water because you’re not going to fill it with hot water. Well now they are spoiled and won’t drink unfiltered water. We tried to give them unfiltered water once and it just sat there for like two day almost untouched. Spoiled little assholes would die within a week in the wild.
I also believe a vehicle of just about any size bigger than like a golf cart should do the job.
