I’ll walk your dog wherever you usually walk your dog, as long as that is reachable by foot. I do not drive so will be unable to take your dog on a trip.
One thing to note is that other than exceptional pre-agreed circumstances, your dog will be on-lead with me on walks. If your dog is used to being off-lead and there are places where being on-lead would be stressful for your dog, I will likely avoid those places. For example, some dogs are unhappy at being on-lead when around other dogs that are off-lead.
