How often are people taking their dogs here in winter?

All the time. I'm taking a clients dog there today

To add to the other responses, especially on a day that's warmer than the previous day(s). You may not enjoy the Dog Party that typifies a trip in the other three seasons. But you'll also meet breeds that are happier in the cold/snow that are absent or lethargic in the "heat."

All the time. Many go even when it's muddy 😊
