Story
You can fill out an adoption application online on our official website.Rhino is a handsome 2-year-old Cane Corso with soulful eyes and a quiet, thoughtful presence. He can be shy when first meeting new people, but once he feels comfortable, his gentle and affectionate personality begins to shine. He forms meaningful bonds with those who earn his trust and has a soft spot for the ladies. Rhino is crate trained when left alone and does very well overnight outside of the crate. He has experience being around dogs of many sizes and personalities and generally does well, especially with appropriate introductions and clear expectations. He has a solid foundation of training and shows good potential for continued growth. Rhino’s foster mom is actively working with him to build confidence, reinforce structure, and support positive behaviors as he prepares for his forever home. Transition & Training Support To ensure Rhino’s success during adoption, there will be a 4–6 week training and transition period with his foster mom as he moves into his new home. This period is intended to provide continuity, consistency, and guidance during a major life change. The goal is a smooth transition that supports Rhino emotionally and behaviorally while setting clear expectations for long-term success. Adopters should be prepared to participate in this transition process and maintain the routines and training strategies that have already been established. Ideal Home & Adopter Expectations Rhino will thrive in a home that understands large-breed dogs and values structure, patience, and ongoing training. His ideal home will include patient and consistent adopters who allow him time to adjust and build trust; a willingness to actively participate in the 4–6 week transition and training period; clear structure, routine, and boundaries; experience with large or guardian-type breeds (or a strong commitment to learning); proper dog introductions and ongoing social guidance; an  an understanding that training is an ongoing process, not a one-time solution.A calm, supportive environment with clear communication will allow Rhino to grow into theconfident, loyal companion he is capable of becoming.SummaryRhino is a gentle giant with a soft heart who is looking for an adopter ready to invest in him,guide him, and appreciate his steady, meaningful bond. With patience, consistency, andcontinued support, Rhino will make an incredible lifelong companion Visit this organization's web site to see any additional information available about this pet.January 15, 2026, 4:27 pm
