“I spent time growing up on ranches in break from school running around with tons of dogs! I always look forward to pet sitting relative’s pups and giving them a few special days with treats and adventures. I love hiking and swimming in rivers and lakes! l am learning more about the pet service industry and can only hope to grow and learn more techniques to create a fun environment for the pups in my care. I am eager to learn about each dog’s personality and learn what they like to make their pack walks enjoyable. I look forward to spending quality time with the pack and creating a bond that will make our walks fun and exciting!” -Nina
