Logo for NW Dog Walking Company featuring a silhouette of a dog and trees, with text 'Est. 2016', 'NW Dog Walking Company', and the slogan 'Your dog, our passion!'

NW Dog Walking Company was founded by veteran dog walker, Holly Cook, who has over 30 years of experiencing working with dogs in a professional capacity. It is estimated that Holly has walked over 25,000 miles in her dog walking career!

We focus on individual walks over pack walks. Your dog receives one-on-one time with their new best friend.

You will be able to follow along on their walk and receive a report card at the end of the walk.

Your Dog.
