First I want to say that If your dog isn't reactive, Lauren would probably be a fine sitter. I mostly chose Lauren because when we went on our meet and greet she wasn't phased by Coda (my dog)'s reactiveness and seemed very confident that she would be able to handle it. Coda and I worked together for a couple weeks on improving her reactiveness and before I left her with Lauren and based on her constant improvements I had full confidence that she would be a regular, non leash-reactive dog within a couple months. Lauren took care of her for a little more than a week, and they got into a bad situation the 2nd day. Lauren was communicative about it which was good. But I think it left them both very anxious. By the time I got back Coda had changed from a dog that would lunge at 1 in 50 people, and get stiff around 1 in 20 to a dog that barked and lunged at every person. Her dog reactivity has also gotten worse, before she'd bark, but was much more easily distracted. Now she barks and lunges at every dog. Before Lauren took care of her I had full confidence that she'd be a happy city dog in a few months. Now I'm not sure she'll ever recover, she clearly had a pretty traumatic time. So while I'm sure Lauren would probably be fine for a non-reactive dog, I would strongly caution against having her take care of your pup if they have reactivity issues.
