We used Michael's service from Oct 2015 to Dec 2016 and were enormously impressed. From the moment he walked through the door he exuded a calm, confident energy that is critical around large dogs.
My husband and I have 2 Rotties with very different personalities. One is lazy but wary of human strangers while the other is high energy and moderately dog aggressive, but both of them loved Michael immediately. Not only does he balance the needs/capacity of our two very different dogs, he somehow managed to socialize our trouble child with other dogs and sent us pictures to prove it! He successfully took them for pack walks; I wouldn't have believed it unless I'd seen it with my own eyes. Michael is amazing!
He's responds quickly to text messages and is flexible with re-schedule/adding walks. He's even thoughtful and kind enough to bring in packages from our doorstep if anything's been delivered during the day.
Knowing that he's fully bonded & insured made the choice a no-brainer. Handing over your house keys to a complete stranger can be difficult, so knowing that Michael is fully covered is icing on the cake. He has a flexible payment schedule and accepts eTransfers.
