Pet care experience

Friendly Neighborhood Dog Lover

I am officially a certified dog trainer through Penn Foster!! I adore dogs but love all animals in general ❤️ I have 4 dogs of my own and a bearded dragon! I currently balance working at Wheaton Animal Hospital as a kennel attendant and a bather. In the past I have worked at Camp Ruff It as a daycare attendant, so I have worked with multiple dogs at a time. Occasionally do nail trims as well!!

House Sitting • Aug 13, 2026

Marissa was so kind and professional with Murphy. He really was attached to Marissa with her house sitting, I am so happy with Marissa.

I would like to know things like triggers (ex: my dog doesn’t like her butt rubbed), things I need to watch out for (ex: your dog likes to chew cords or has to pee frequently), and any health concerns or conditions (ex: food allergies)
