A park we stay at every summer had a pet sitting and walking service for several years. They dropped two years ago due to an employee suffering a serious injury (fell off the stairs and broke their ankle) attempting to stop a dog that shot out of the RV door when they were entering the rig to walk it. Though it eventually turned out fairly well, the employee suffered a permanent injury, the pup was finally captured 8 hours later and was extremely scared and also suffering from injuries. There was the potential for lawsuits against both the park and the people that owned the dog. Lots of stress, tension and potential ill will was created, along with the permanent injury. Just keep the risks in mind if you have someone unknown to you watching your pet. BTW, the dog was a toy poodle, not a large or vicious dog of any kind.
