He's non-destructive and a pro at taking his medicine with ease.

Someone who enjoys leisurely strolls because Finn walks like a true gentleman on the leash! Interested in Adopting?

Story
You can fill out an adoption application online on our official website. Shelby, a 3-year-old Neapolitan Mastiff, entered our rescue in late 2021 after a challenging start at a commercial breeder auction. In early 2022, she found a loving home and became part of a family. Unfortunately, due to unforeseen health issues affecting her dad, Shelby is now returning to us, seeking a new chapter in her journey. Shelby shared her life with two male bullmastiffs. As she embarks on this new phase, we are specifically looking for an individual or family with Neo experience or experience with similar giant guardian breeds. Shelby thrives as the only female dog, and we believe a home with this dynamic will ensure her happiness and well-being. If you have the capacity to provide Shleby with a secure and loving forever home, please fill out the application linked below. Your support can make a significant impact in offering Shelby the second chance she truly deserves! https://www.mastino-rescue-inc.org/familyprofile Visit this organization's web site to see any additional information available about this pet.April 24, 2024, 8:42 pm
