KSR Pet Care consists of a team of mature employees and office staff who were all thoroughly screened before joining. We get selected for our maturity, flexibility, affinity and experience with pets, joy in helping others. We possess the passion and commitment to offer you the best in pet care.

For us, transparency, integrity, security and safety are key in delivering excellence in pet care services. We assign one primary walker/sitter to bond with your pet. A manager and back-up sitter are also assigned.

The relationship with KSR's clients (humans and pets) is both caring and professional. We consider well-being, safety and security are top priority when it comes to your pets. Our visits are set up to allow a stress-free environment, so your pets are happy, have fun while being well-taken care of at the same time. We therefore spend time with you before starting service so you can get to know us and we get to know you, we get detailed care and house notes which are stored in your profile. A manager is present at each new client consultation to ask questions and take notes while our sitters are there to engage with the pets and get fully prepared for the first pet visit.

Pet clients become part of the family and at the same time KSR Pet Care delivers highly and professionally by thinking outside the box and using experience and common sense in pet and house care. We strive for open and honest communication with our clients before, during and after service.

We are CPR & Pet First Certified and some of us are skilled in administering subcutaneous fluids. Our sitters send text updates and/or leave written notes per visit. We also have a GPS tracking program in place which records a time and location stamp of the sitter per visit. This system allows us to ensure professionalism and accountability but also security and safety for our sitters.

Our team consists of 25+ staff members who we carefully select: we love working with mature animal lovers of all life stages who are passionate about working with animals long-term. 50% of our staff members are dead-set on having a part-time or full-time career in pet care. To help them in their careers, KSR Pet Care offers decent wages as well as benefits: AFLAC, health care (medical, dental, vision) and retirement. Over the years, sitters moved away out of state or out of the country, but we are proud to say we also have 6 sitters who returned and started working for us again. Because this is their passion!

 Meet The Owner

Karen Rosenberg lives with her husband in McLean, VA. She has four furry kids: three dogs and one cat. There is Lexie a sable German Shepherd, rescued from Virginia German Shepherd Rescue (VGSR), born in 2006. Handsome Harry the junior Korat mix cat, rescued from Last Chance Animal Rescue, born in 2006. In 2013 she adopted Jiffie a golden lab mix, rescued from Homeward Trails Animal Rescue, born in 2010. Cody was adopted early 2017 from Mutts Matter Rescue who looks like a puppy but was born in 2007.

Karen is originally from Belgium where she obtained a Master's degree in Germanic Languages (English and Dutch) at the Catholic University of Leuven as well as a post-graduate degree in business administration. Karen is pictured here with Cody and Jiffie. She still misses her pets who went over the Rainbow Bridge: Luka, her first dog and chowchow/keeshond mix, left this earth in Nov 2015 and little calico cat Sally died way too soon at age 8 in Jan 2014.
