Story
Meet Garcia  Garcia is truly a survivor. He came to us from the brink of starvation and has fought his way back to health, confidence, and purpose. Now, at just 9 months old, he’s ready to become the incredible dog he was always meant to be. Garcia is a guardian-breed mix (Boerboel, Neapolitan Mastiff, Pit Bull, Cane Corso, and Rottweiler), and he carries all the traits that come with that: loyalty, intelligence, drive, and a strong desire for structure and guidance. He has been training daily with @honorbrightdogtraining and Janice, and he has absolutely flourished. Garcia looks to his people for direction, learns quickly, and thrives when given a job and routine. He has a lot of energy to burn and will do best in an active, experienced guardian-breed home that understands his needs. Garcia would love a large, securely fenced yard where he can run, play, and enjoy his beloved toys. He has done well with other dogs but would also be perfectly happy as your one-and-only. What he needs most is stability, consistency, and leadership. This special boy has overcome so much, and now he deserves a home that can help him continue growing into the confident, balanced guardian he’s meant to be. We are looking for a guardian-breed experienced home to complete Garcia’s journey. You must be over 21 to apply and live within 2 hours of the Lehigh Valley, PA area within NJ or PA.

Story
Meet Miracle! They say everyone could use a little miracle in their life, and we happen to know one with four paws and a wagging tail. This 4-year-old, 65-pound Mastiff/Boxer mix came from a hoarding situation and raised a litter of puppies just six months ago. Now it's finally Miracle's turn to be cared for. She is incredibly sweet, calm, and affectionate with people, with a gentle nature that makes everyone she meets fall in love. Miracle is eager to please, seems to genuinely want to follow directions, and should be very receptive to training. She also walks nicely on a leash, especially for a dog her size. Miracle gets along well with other dogs, although she may need to be separated for feedings as she may guard her food. She would likely do great with children and can be cat tested if needed. If you've been waiting for a sign that your perfect companion is out there, maybe this is your Miracle. Apply at lvpeaceablekingdom.info.

Meet Nebula! Nebula is a smart girl who's eager to learn and wants so badly to get it right. She's full of potential and has already shown that she picks up on training quickly with structure and consistency. After she's had an outlet for her energy, she's all about soaking up affection from her people. Like many young, energetic dogs, Nebula is still learning how to channel her excitement. When she gets overwhelmed, she can forget her manners, so she'll do best with a family that's committed to continuing her training and giving her the structure she thrives on. Nebula would make an amazing adventure buddy for someone who enjoys hiking, exploring, or staying active. Apply for this fun girl today! Our dog adoption fee is $350 (not including tax) which includes each animal fixed, up to date on core vaccines, microchipped, kept on monthly preventions, and dewormed.
