Late in the evening their are many home owners on the local course that come out and throw balls for their dogs along the rough next to the fairways. There is a high degree of community movement in and around this particular course, it's kind of known for it. People out for walks on the cart paths and cutting through the course on foot in order to get home faster. I suppose that would come to an end if it was a problem.
I did have one incident with four dogs off leash approaching me on a green, they appeared to be in that in-between friendly and not friendly state. I honestly prepared for a confrontation (I know that they sense that and respond in kind) and yelled for the owners to call their dogs back. The dogs immediately circled back to their owners. I didn't like sounding like an ass, but that lead dog had his head low and was purposefully coming toward me, the others were on his flanks and it was clearly pack behavior. I think the owners were a little embarrassed that their little darlings had upset me.
I do think that all superintendents should have a dog as a companion and goose chaser out on the course. Here is a blog about a golf course dog:
