Dogs depend on people for love, attention, food/water, exercise, and so many other things that are important to ensure a caregiver understands. My love for exercise results in plenty of walks for your dog! I have quite a lot of experience in house sitting, with the longest stint being 2 and 1/2 weeks. Having lived independently at a young age, I understand the importance of maintaining a clean house/apartment and always leave with a cleaner house/apartment then its original state. As for walking and running, I am more than happy to do either, or both, with dogs of any size. I have experience with dogs living in urban areas that are not okay with other dogs, which is fairly common.
