I can be very spritely and playful, as well as patient and understanding. Your dogs will always have the best time with me, no matter what type they are. I have owned a calm dog and a very anxious dog, and get along with both easily. I have also watched large dogs and walked large and aggressive dogs and have not had any issues. I have walked dogs for several miles, so it isn't an issue if your dog likes to be walked for a long time. It also isn't an issue if your dog is aggressive because I have experience with aggressive dogs. Getting to be around dogs all day is my dream, and I will always ensure your dog is happy and safe.
