Story
Hi, I'm Mama! I'm a 106-pound Mastiff mix with a whole lot of love to give! My friends at the shelter call me a gentle giant, and once you meet me, you'll understand why. I absolutely adore people, love being brushed, and will happily soak up all the attention you're willing to give me. I'm also a big fan of playing fetch, so don't let my size fool you into thinking I'm only interested in lounging around! I enjoy getting outside, but I do have to admit something: I'm VERY strong on the leash, and sometimes my excitement gets the best of me. I'll need someone comfortable handling a big girl like me who can help me continue working on my walking manners. My compatibility with other dogs and cats still needs to be evaluated. If you've got room in your home for a big personality and an even bigger love bug, I'd be happy to meet you! 📍 The Center for Animal Health and Welfare PA Kennel License #02941 1165 Island Park Rd, Easton, PA 18042

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.

Story
Big guy, big heart, and so much love to give! Meet Lee, affectionately known as Bulli, a handsome brindle Mastiff/Pit Bull mix who is looking for a second chance at happily ever after. Through no fault of his own, his owner was no longer able to care for him, and now this sweet boy is searching for a family to call his own.Don't let his big, tough-guy looks fool you! Lee is a total sweetheart who loves being close to his favorite people. One of his favorite things to do is sit between your legs or lean his big body right into you for some extra love. He's a big snuggly guy who wants nothing more than to feel safe, loved, and part of a family.Lee is an active boy who loves to play, have fun, and enjoy life! He's also a fan of tasty treats, especially apples, peanut butter, and bananas. And here's some great news for his future family: Lee is both housebroken and crate trained!Lee gets along with kids, but when it comes to other dogs, he's a little more selective. He needs proper introductions and canine companions whose personalities and play styles are a good match for his. The right dog friends are out there; they just need to vibe with him! And despite his big, brave appearance, Lee has a softer side that comes out during thunderstorms. When the skies rumble, he gets scared and could use some extra reassurance from his people. Even big guys need comfort sometimes!Lee isn't asking for much. Just a home where he can be loved for who he is, a family to share adventures and couch time with, and people who will let him lean into them when he needs a little extra affection.Could you be the one Lee has been waiting for? If you're looking for a loyal, playful, affectionate big guy with an even bigger heart, Lee (Bulli) might just be your perfect match! Adopt Lee. Give this handsome boy the loving home he deserves.

Story
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.
