Here are fun facts his owner wants you to know: - Twix / 3yo / Male/ Neutered / 65 lbs / In great health - Mastiff/Herding mix - Up to date on vax since 8/25/25 - Will do best with experienced, active dog owners who would be able to be consistent with good daily habits to strengthen his foundational training.

He is passionate about learning. - Housetrained and very communicative about needing the bathroom. Will whine/grumble, give paw or look at door. - He is crate trained and loves his crate. He will crate himself to take naps throughout the day and also will tuck himself to bed when the sun goes down and sleeps through the night. - Not destructive in the home at all, even when left alone. No separation anxiety. - Walks nice on leash! Big sniffer. Knows heel. - Energy level is average/medium. Will match your energy to be very active or a couch potato. Greets with excitement for just a few minutes. - Shines with his family/pack and loves physical and verbal affection. - Total silly playful goofball and sweetie pie who just wants to love. - Loves long walks (hiking and camping), swimming, tug and fetch. - Nervous when not introduced to new dogs and new people but eased with structured introduction or pack walk. 100% success rate when introduced to new people.

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.

Rajah

Mastiff

Male, Young

South Plainfield, NJ

Size

(when grown) X-Large 101 lbs (46 kg) or more

Details

Good with kids, Needs experienced adopter, House-trained,

Story

Rajah is a 110-pound Bandog who will be 2 years old on July 28th. He is deeply devoted to his family and is incredibly affectionate. Making the decision to rehome him has been heartbreaking, but we recognize that he needs an environment better suited to his breed and temperament. Rajah is a powerful guardian breed with strong protective instincts and is aggressive toward unfamiliar people. He is not a dog who is comfortable meeting strangers or being introduced to new people casually. We invested in professional training, but his natural guardian instincts remain. He will need an experienced owner who has previously owned or handled large guardian breeds and understands how to safely manage a dog with stranger aggression. We have had very limited exposure to other dogs and cats, so we cannot confidently say how he would do with them. There is no adoption fee. Our only priority is finding the right, experienced home where Rajah will be safe.

Story

At 8 years old, King Shady is a gentle Mastiff mix with a heart as big as he is. While many dogs his age are overlooked, King Shady is hoping someone will see beyond the gray on his muzzle and recognize the loyal, loving companion waiting underneath.King Shady enjoys the simple things in life. He`s always excited when it`s time for a walk, but once he`s outside, he settles into an easy pace and enjoys strolling by your side without pulling on the leash. He`s social with people, happy to meet new friends, and absolutely loves gentle pets, belly rubs, and spending quality time with the people he trusts.This handsome senior isn`t looking for adventure—he`s looking for a home. A quiet place where he can finally exhale, stretch out on a cozy bed, and know he belongs.King Shady is searching for an adult-only home where he can be the only pet. He can be reactive toward other dogs and has resource guarding behavior around food, so he`ll thrive with an experienced adopter who understands his needs and can provide a structured, predictable environment where he feels safe and secure.Toys don`t really interest King Shady—his favorite things are leisurely walks, relaxing with his people, and soaking up affection. If you`re looking for a loyal companion rather than a high-energy playmate, King Shady may be exactly who you`ve been waiting for.Senior dogs have a way of loving with their whole hearts. They don`t ask for much—just kindness, patience, and a place to call home. In return, they offer unwavering loyalty and quiet companionship that is truly priceless.If you have room in your heart and home for a gentle giant who deserves a second chance, come meet King Shady. He may just be the missing piece you`ve been searching for.To complete adoption questionnaire: https://hamiltonmcnj.seamlessdocs.com/f/AdoptionApplicationTo see other available animals: https://www.hamiltonnj.com/173/Pets-Available-for-AdoptionHamilton Township Animal Shelter cannot offer any guarantees on the age, health, temperament, personality or mental disposition of any pet.
