Safety, trust & environment

I will treat your pet as if they were my own. I will do my best to stick to their routine so that they can feel comfortable and safe while their favorite humans are away

Information Marissa D. would like to know about your pet

What is your general routine? Does your dog have any special interests or needs? Are there certain commands that I should know? Where are your dog’s favorite places to be pet?

A typical day

I will do my best to match your routines with your dog! If you have a high energy pup, I will play his or her favorite games and take walks or run together to get out that energy. If you have a more mellow kind of dog, I will gladly sit and snuggle all day.

This is the second time we’ve relied on Marissa for dog sitting / house sitting and she does an excellent job! Marissa is an excellent communicator, asks greats questions, and follows all instructions. She takes such great care of our dog Velveeta and she sends regular updates and photos. Our home was spotless when we came back from a week away. Thank you, Marissa!

Philly happy!! That says it all. Marissa was great to work with. She was always on time, communicative, and handled a complication in my timing with ease.

Marissa was awesome. She loved our pups so much when we were away. We came home to a clean house and happy pups. Allie was telling me all about it. She sent pictures daily and responded when immediately when I texted her. So glad we finally found our go to sitter.

Each sitter joining Rover needs to pass a background check. And by booking on Rover, you can get photo & message updates, 24/7 support, and reimbursement for eligible vet care.
