Kristen watches my very “sensitive” pitbull. My raya was a rescue dog that had been in two dog fights. As such she very nervous around new people and other dogs. Much to my surprise she immediately took to Kristen upon meeting. Kristin came over a few more times before being alone with raya but I knew from the first time we would have no issue. After leaving town I got all kinds of cute pics of Kristin and raya playing, cuddling, etc. she was able to successfully exercise her with no incidents. Raya slept with her haha which really surprised me. I would say Kristin’s love for animals, and her happy nature really put raya at ease , which is always a big fear for me. As I said, she is typically scared of everyone … which leads to her lashing out , but we’ve never had a problem with her when she’s with Kristin. I highly recommend Kristin , and continue to use her to this day. I should add I all’s have 4 cats who all like her as well, but they are not my typical issue, it’s usually raya :)
