I have worked at best friends Kennel for 2 years. i have experience with handling all types of dog from little chihuahua to the massive breeds like the Great Dane or the English mastiff. My favorite breed. is the German Shepherd. I have 3 rescue dogs myself, a collie mix and a great Pyrenees and a German Shepherd. I would ask that the owners of the dog leave a list of their commands just so i know the proper way to deal with your dog if i wanted them to sit or follow a command. i have no problem with dogs that are dog aggressive or leash aggressive, my own German shepherd is quite nasty while on lead so i am always looking for others walking their dogs so i can cross the street to avoid a conflict. I have no problem with giving dogs medication. Besides the list of commands i ask that you leave emergency contacts that I could refer to in case I was unable to reach you in a time of emergency.
