I'm not sure about other pet owners here, but I would want to know what other dogs were going to be around my dog and see how they interact before I booked. Such as the sitter's pets but I would not be comfortable if there were going to be other customer's dogs interacting with my dog that I did not get to do a meet and greet with. I have a lot of time, love, and training in my dog and would be devastated if she were hurt by another customers dog. My dog is not dog aggressive and I am new to this site and maybe it's normal for people to have more than one dog stay at a time but I would want to know if there were going to be strange dogs before I booked.
