Rex is an 85-pound neutered male German Shepherd with a strong working dog spirit and unmatched loyalty. He found his way to safety from a South Texas animal shelter, where he faced dire circumstances, coming to us underweight and stressed. Today, he's thriving and has regained his health, showcasing what a stable home can do. Having had prior Schutzhund training, Rex is smart and eager to learn. He responds to German commands, enjoys tasks, and is committed to his work as a protector. He excels in house manners and walks well on a leash, displaying a remarkable recall. While Rex is affectionate and loving towards the women in his life, he possesses protective instincts, making him wary of men. Thus, we seek a female adopter or a female-led household that can fully understand and respect his needs. Rex has a documented bite history related to resource guarding, stemming from his past as an underfed shelter dog. It's crucial for his new family to respect his boundaries around food and resources as he adjusts to a stable environment. Rex is not just another dog—he’s an intelligent, loyal companion that requires an experienced, confident home that can provide him with the structure he thrives on. Rex needs a forever home where he can bond with a woman who genuinely understands the nature of German Shepherds. His ideal person will be willing to continue his training, respect his protective instincts, and be committed to a lifelong companionship. Additionally, Rex is heartworm positive and will need treatment. We believe placing him in his forever home before beginning treatment will help him adjust better to the process, and our rescue is here to assist with the costs of his care. Rex deserves stability and love, having faced enough uncertainty in his past. If you think you're the right person to give Rex the loyalty and affection he craves, please consider making him part of your life. Think you are the one? Submit an application!
