Story
Meet Fiona 💕 Fiona is a beautiful Neapolitan Mastiff estimated to be around 3 years old. It’s very clear that she was used extensively for breeding before coming to us, and despite everything she’s been through, she is nothing short of incredible. She is incredibly sweet, gentle, and affectionate. Fiona has a playful side but is overall a super chill, easygoing girl who truly loves the simple things like cuddling, belly rubs, and being close to her people. She has the kindest soul and a very soft presence. Fiona is non-reactive and tolerant around other dogs, but she would do best as the only dog in the home. Due to the heavy facial folds common in her breed, her vision is not the best, so fast-moving dogs, especially during playful moments can sometimes startle her. She does have severe hip dysplasia, likely a result of being bred repeatedly, and she will need a home that understands and can manage her orthopedic needs. When Fiona arrived, she was very underweight, but with proper care and nutrition, she is slowly and steadily putting healthy weight back on. We are looking for a home with mastiff or giant breed experience, someone who understands her structure, limitations, and the special care she deserves. One of the sweetest things about Fiona? Sometimes she sings and it is absolutely adorable. Fiona has so much love to give and deserves a calm, understanding home where she can finally just be a dog, loved, safe, and cherished by her humans. If interested in meeting Fiona, please apply on our website today! https://www.underdogheroes.org/applytoadopt

Story
How this pet arrived: Clifford was brought in by a community member on January 30, 2026. Why this pet is the one for you:Meet Clifford (yes... he really is big). True to his name, Clifford is a big dog with a big heart-and sometimes big feelings too. This gentle giant can feel unsure around new people, especially men, so he needs humans who will proudly advocate for his space on walks and when visitors come over. Giving him time and calm introductions helps him feel safe. Clifford's size may be impressive, but his nature is soft and sensitive. He's best suited to a home with children aged 8 and up who can respect his boundaries. Clifford came to us as a stray, so his past is a bit of a mystery, but he's ready to grow something even bigger than himself: trust, confidence, and a home.Shy/Fearful Dog: This pet requires a virtual behavior consult, please watch THIS video to learn more about them. Primary Color: Red Weight: 134.4 Age: 1yrs 10mths 2wks
