I have been walking and exercising dogs for 15 years for clients, friends, and family. Because my dog was a very active dog, we usually took on other very active dogs too. Dakota taught me that exercise isn't just walking. Dogs need variety. For elderly dogs, this might simply be slow walks and lots of sniffing. Sniffing is essential mental exercise even though it gets boring to us. For active dogs, whenever possible, we would go on excursions for an hour or more which involved walking, running, swimming, and playing. My hours and schedule are flexible. I will tailor the exercise to what your dog wants and needs.
