Walker Needed For 1 Dog In Ponte Vedra Beach

My 28 lb. Jack Russell mix, Beau, loves people, but isn't getting along well with other dogs. We are looking for someone who could occasionally either stay with him at our place when we go out for 3-4 hours, or who we could bring him to(but again, in case you have pet(s) of your own, he doesn't get along with them often). Taking him on a leashed, short walk when caring for him would be helpful. We would also love to find someone with whom he could board, or who could stay at our place (on the beach!) with him, if we go out of town (which we only do rarely). Thanks!
