Story
At 8 years old, King Shady is a big-hearted Mastiff mix looking for a calm, understanding forever home. He may be a senior, but he’s still full of life and has plenty of love to give.When it’s time for a walk, King Shady is eager to head out but settles nicely once he’s outside—he doesn’t pull on leash and enjoys lumbering along at his own pace. He’s social with people, calm and curious when meeting new friends, and enjoys gentle pets and attention. With his handlers, King Shady is affectionate—he’ll lean in for scratches, roll over for belly rubs, and happily soak up time spent together.King Shady will need a home where he is the only pet. He can be reactive when seeing other dogs and should not live with children due to his resource guarding behavior around food. His perfect match is an experienced adopter who understands his needs and can give him a safe, structured environment where he can relax and shine.While King Shady isn’t interested in toys, he’s more about the simple joys in life—steady walks, quiet companionship, and people who respect his boundaries. He has so much love to give to the right person who can see past his quirks and offer him the stable, loving home he deserves.If you have a soft spot for seniors and experience with large breed dogs, King Shady might just be the loyal companion you’ve been waiting 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.

Make A Difference in your Community - Adopt a Shelter Dog! Would you like to foster a Shelter Survivor? For more information, visit us at www.sheltersurvivors.com THIS IS A COURTESY POSTING – Twix is not in one of our foster homes and we have not met him, we are assisting his owners with finding him a new home. 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. No other animals, no small children in the house. - Has had multiple professional training experiences, all successful. Quick improvements in training sessions. 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. Selectively reactive with intact males. - No cats is best. He is ok with cats if the cat leaves the dog alone. He lived 2 years with a male cat and they kept to themselves and lived peacefully. - Not socialized around kids. Unknown. - Resource guards around main meals and high value treats, but not with training treats. Very easy to train (food motivated). Does not protect empty bowl. - One bite due to mishandling by his previous owner. The dog was nervous around a stranger and the previous owner did not intro or deescalate then dropped leash. After a professional reactivity evaluation, a trainer assessed him to be safe and not serious about bites. - Previous owner got him as a puppy from a friend’s litter.

Story
Despite the old saying, sometimes good things do come in BIG packages! That’s certainly the case with Method Man, as this gorgeous guy tops the scale at 112 lbs. If you’d prefer to play in the yard, MM would be happy to oblige, as he’s a pretty laid back guy. But as long as you let him carry a stick, he’ll trot by your side when you go for walks. (Perhaps he thinks the stick is a cool accessory, meant to impress other dogs?) When it’s hot outside, Method loves nothing better than a nice nap on a cool floor, but he prefers to snuggle with a blanket when the weather turns cold. This adorably wrinkled guy is very smart and already knows his commands, and his motto should be ”will work for hot dogs!” Since his owner had to surrender him due to housing issues, Method Man has been very anxious to find his forever home. He prefers to share a home with just his human companions, and will make a wonderful addition to the right family. MM loves playing with stuffed toys, and will entertain his new family with an occasional case of the zoomies. If you decide to share your life and your home with this lovely pup, you’ll be rewarded with loving looks from his very soulful eyes. Adoption by appointment only withan approved application. Please go to www.easelnj.org/adopt to submit an adoptionapplication. Someone will be in touch within 48 hours. Adoption by appointment only with an approved adoption application.

Story
**🚨 URGENT – BONDED SENIOR SAINTS FLEA & TICK WERE DUMPED TO DIE 🚨 💔 THEY NEED A HERO IMMEDIATELY 💔** Flea and Tick are two bonded senior giants who gave their whole lives to someone… only to be dumped like trash when they needed love the most. These gentle souls were abandoned, confused, and heartbroken—left to die with no one to speak for them. Today, we speak for them. These two sweet seniors are the definition of gentle giants. They are calm, quiet, loving, and so easy to care for. Their eyes tell you everything—they’ve been let down, but they still believe someone out there will finally choose them. ❤️ About Flea & Tick: • Bonded seniors who MUST stay together • Giant-breed (Saint Bernard–type) sweethearts • Gentle, calm, soulful, and unbelievably loving • Kind, patient, and craving affection • Great couch companions, perfect for a quiet home • Don’t require much—just safety, soft beds, and love 💔 Their reality: Because of their age and size, they are at extreme risk. Seniors—especially giant breeds—rarely make it out unless a true hero steps up. They will not survive without immediate foster or adopter commitment. 💥 You can be the reason they live. Flea and Tick have already been failed once. Please don’t let that be how their story ends. They deserve warmth. They deserve comfort. They deserve a family that sees their worth. These seniors do NOT have time. PLEASE HURRY TEXT KAREN 4136298152
