Amanda Flores-

Dog Walker & Pet Sitter

I would like to introduce you to our new pack leader, Amanda Livi. Amanda has a high level of professionalism and integrity from past work experience. Amanda is very alert, caring, goes above and beyond, learns quickly and takes initiative with the dogs best interest always in mind. Amanda has a degree in Liberal Arts, and is an artist. She has lived with dogs her entire life and wants to adopt a border collie. She is from Texas, loves California weather and adores the outdoors. 

"My husband and I moved from Texas to the East Bay and it has been an absolute joy exploring the beautiful California trails with the pups at FitDogTheory! I am an artist who specializes in print making, acrylic painting, and graphite/charcoal and I find constant inspiration in the positive attitude the dogs always posess. It's impossible not to get caught up in their excitement when I pick them up for pack walks. Knowing that we are keeping each other fit is just the icing on the cake!"
