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

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.
