Availability

I am currently a college student, so my schedule varies slightly during the semester. However, I maintain a consistent routine and am reliable with planned visits, especially in the mornings. I commute from Sag Harbor and appreciate having a weekly schedule in advance to ensure consistency and dependability. During winter and summer breaks, I have a much more flexible and open schedule.

Safety, trust & environment

I provide my own pet-safe wipes to clean paws after outdoor walks, helping keep your home clean while maintaining your pet’s comfort. I’m mindful about the products I use and prioritize gentle, pet-safe options. I always ask before giving any treats and make it a priority to respect both your home and your pet’s routine. I aim to provide thoughtful, considerate care in every environment I’m welcomed into.

Information Marissa S. would like to know about your pet

I value clear communication and mutual respect. I always treat your home and pet with care and professionalism, and I work best with clients who provide clear instructions and share any pre-existing health or hygiene conditions so I can ensure the best care possible.

A typical day

During each visit, I focus on keeping your pet comfortable, active, and cared for. I start by checking in on your pet, then take them out for a walk or potty break at a pace that suits them. Afterward, I handle feeding based on your routine. I also keep an eye on their behavior and overall well-being, and before I leave, I make sure they’re settled and comfortable. I always send an update so you know how everything went.

Pet care experience

I began working with dogs at a young age by starting my own dog-walking business at 12, and I have continued building my experience in pet care ever since. I have hands-on experience with dogs of various sizes and temperaments and am confident handling a range of needs, while continuing to expand my experience with larger breeds. In addition, I have volunteered with the Animal Rescue Fund (ARF) in East Hampton, where I worked with dogs of diverse backgrounds, strengthening my adaptability and overall handling skills.

To Whom It May Concern, I am delighted to provide a reference for Sadie, who has been an outstanding dog walker for my [dog’s Moët and Chandon , ] over the past 2 years ]. From the very beginning, it was clear that Sadie has a true love for animals and an exceptional understanding of their needs. Sadie is consistently punctual, dependable, and communicative. She always takes the time to ask about my dog’s specific needs and preferences, ensuring that each walk is both enjoyable and tailored to my pet’s unique personality. I’ve seen a noticeable difference in my dog’s energy levels, behavior, and overall happiness since we began working with Sadie. What truly sets Sadie apart is her genuine affection for animals and her proactive approach. She keeps me informed with updates and photos during and after each walk, which gives me peace of mind. I can trust Sadie completely to provide my dog with a safe, fun, and enriching experience. I highly recommend Sadie to anyone in need of a dog walker or pet care provider. Her professionalism, dedication, and warm, caring nature make her an invaluable part of our pet care routine. Please feel free to contact me if you need any further information. Sincerely, MG
