Love Ollydog, my favorite is the 'Alpine Reflective Harness'. My dog doesn't love when a harness has to go over her head to get it on, and has a large head to body, so it's often not very easy to get it back off if it was well-fitted on her body. This harness has buckles on both sides, so I always just unclip one side completely and have her step into it when we're getting ready to walk. She doesn't mind this at all, and it's super adjustable! I've had my first one for almost 2 years and it's starting to show some wear, but after using it at least 3x per day for 2 years, that's to be expected. I have a back-up now that I rotate between. There are d-rings to clip a leash both on the front/chest area and on the back, depending on what works best for your dog.
