Safety, trust & environment

When I stay in your home, my goal is to make it like I was never there. I am a very clean person so i clean all dishes I may use, and I aim to have the smallest footprint possible while giving the best care to your fur babies. I will also do check-ins with pictures in the morning/nigh based on request. I have also taken care of dogs at my personal home. At my house, I have a large, fenced in backyard and a friendly GSP/Lab mix who is 8. My home is also quite large and i have my own room in which your fur babies would stay with me.

Information Marissa O. would like to know about your pet

Prior to caring for your babies, i would love to make time to meet them along side you. this ensures that when i meet your fur babies it's not only in a controlled environment, but also with the it's alongside the people they trust. i am also more than willing to accommodate any rituals they may do, or any medications they need.

A typical day

I will match your dogs energy. If they're are a low energy dog, i will plan tasks that are low energy and don't place them outside of their comfort zone. If your dog is High energy, i can match and play with them to help them stay stimulated

Marissa did such an incredible job with my dog while I was away for a few days on a trip! My dog loved her and she took amazing care of him with photo updates too! Highly recommend and definitely will use her again if she’s available!

Marissa is so dependable and mature beyond her years. She is great with animals and truly is a wealth of knowledge when it comes to the wellbeing of the furbabies. She went well above and beyond and did so in such a kind way. I highly recommend Marissa to care for your pets.
