We retained kristianna for our Labrador, Rascal, soon after we adopted him - it was a tough adjustment for Rascal as a rescue getting into a routine and a new home. Initially Rascal couldn't even be around other dogs and Kristianna had to keep him completely separate for his first outbound trip, but on his next walk, he got Rascal to completely adjust in no time to ride with the other dogs and he absolutely loves his outings now. As soon as the doorbell rings, Rascal dashes to the front door and flies out to the van like a lightning bolt, and returns happily tired each time he goes for his hike, which helps him release his pent-up energy. We highly recommend Kristianna for a dog's fitness and emotional health.
