Neapolitan Mastiff Cane Corso

Female, Adult
Hyattsville, MD
Size
(when grown) X-Large 101 lbs (46 kg) or more
Details
Not good with kids, Not good with dogs, Not good with cats, Needs experienced adopter,
Story
Princess's story began in an abandoned home, where she had been left alone and later discovered to have suffered abuse. When I first met her, she was less than a year old & frightened, thin, and unsure of the world around her but I brought her home so she could finally feel safe. Over the next two years, I cared for her while she slowly grew into herself, though her exact age has always remained uncertain. To strangers, Princess may seem alert, fearful, and cautious, but to those who show her patience and kindness, she reveals her true nature a sweet, loving dog who adores playing, being petted, and snuggling close. She loves her food, she loves her people, and now she deserves a caring person or family who can continue giving her the love, stability, and gentle guidance her heart has waited so long for.
