Availability
I'm currently working part-time, so I have plenty of openings to walk or house sit with your dogs! Unfortunately I am not able to board at this time as I am working with an animal reactive rescue dog.

A typical day
This is all based on what you as the client is comfortable with. I respect boundaries each individual has with their best friend. A walk with light active training is implemented each visit. This can build to more active types of exercise and learning (from tug of war with commands, to obedience training on leash). I'm also open to requests.

Built on Trust. Driven by Dogs :)
Pet care experience
With a deep-rooted passion for animals and years of hands-on experience, I’ve built up my animal experience around understanding and caring for dogs at every level. From running a professional dog kennel to grooming and training, my work is grounded in both structure and empathy. Managing a kennel taught me how to care for dogs in a dynamic, fast-paced environment—balancing health, behavior, and individual needs across a wide range of breeds and temperaments. Through grooming, I developed a keen eye for detail and a calm, patient approach that helps dogs & cats feel safe and cared for. My training background spans both obedience and agility, allowing me to work with dogs not just on discipline, but on confidence, communication, and performance. Whether it’s helping a family dog become well-mannered at home or guiding a high-energy dog through agility courses, I focus on building trust and bringing out each dog’s full potential. This is integrated into my day to day with my own three dogs and will be with the pets I care for. At the core of everything I do is a simple belief: every dog deserves to be understood, respected, and given the opportunity to thrive.
Reviews
Wiliam provides an exceptional level of care that stands apart. His knowledge of canine behavior, paired with a calm and confident presence, immediately inspires trust. He intuitively tailors his approach to each dog-whether managing high energy personalities, or offering gentle attention to more sensitive companions. Every interaction is thoughtful and precise. Knowing my dogs are in his care brings complete peace of mind. William Selina truly elevated standard that discerning pet owners will appreciate.
William has been an absolutely incredible dog walker, and I can’t recommend him highly enough. His knowledge of dogs is immediately apparent—from understanding different temperaments to knowing exactly how to handle various situations with calm confidence. He is patient, attentive, and truly takes the time to make each dog feel comfortable and cared for. What really sets William apart is his ability to handle anything that comes his way, whether it’s managing my high-energy pups, navigating unexpected situations on walks, or giving extra care to more sensitive dogs, like one of my fur babies. You can tell he genuinely loves dogs, and that passion shows in every interaction. It gives me complete peace of mind knowing my dog is in such capable, caring hands. William goes above and beyond, and any pet parent would be lucky to have him!
