We used On The Fly Pet Sitting recently when we were out of town. Mark provided our dog Toby with amazing care and attention 24/7. He took him on hikes, which he really enjoyed, and generally provided him with lots of love and play. Toby is a member of our family and we are usually anxious when we leave him but we could see that he was having such a good time with Mark and that we were able to enjoy ourselves. I absolutely recommend On the Fly Pet Sitting and will be using them again shortly. I would not want to leave my dog with anyone else.
