I have a fenced in backyard for my own dogs that was just rebuilt and checked for holes. Even in the event that something were to happen to it, all that would happen is your dog or mine would end up in another fenced in yard belonging to my neighbors who are reliable and kind. When it comes to anybody else’s house, fencing is great but I will watch the dogs outside regardless of whether there is one or not just to ensure their safety. As for inside my house I do have an open area for relaxation and can accommodate doggie beds if need be. I can work in any environment as long as you as the client lets me know what specifications you would like from me. Just to make sure that doesn’t sound vague, I would just want you to let me know if you want them outside and being watched, if they aren’t allowed on the couch or in a certain room, etc.
