I found Colin when I hurt my back and couldn't walk my dog. My dog is super high energy and needs a good long walk every day. Colin came to meet her and took her for a run with his bike. My dog loved it! Next they started going on pack walks in the Santa Monica Mountains. I really enjoyed watching the videos of their time together. My dog's behavior has changed dramatically since she is getting the exercise she needs. Colin is trustworthy, reliable and fun! I highly recommend him.
