Story

looking for a new loving home for my dog. Hes a sweet, affectionate, and well-behaved boy who deserves more time and attention than I can give right now. I recently accepted a new job opportunity, and with my current schedule, I cant properly accommodate his needs. He is a great dog who loves people, enjoys playtime, and just wants to be loved. He will come with his cage, bed, toys, and food so he can adjust comfortably in his new home. Im hoping to find someone preferably someone with No other pets , and a big yard who can give him the time, care, and consistency he deserves.

Story

TWIX Meet Twix. He is a 3yr old, male Mastiff Shephard weighing 65 lbs. His previous owner got him as a puppy from a friend’s litter but can no longer keep him ☹ Twix is a silly, playful goofball. He enjoys long walks, hiking, camping, swimming, tug and fetch. Twix is very sweet, loves physical and verbal affection. He can match your energy to be very active or can be a couch potato. Twix has had multiple professional training experiences, all successful. He is a very quick and motivated learner. He is thoroughly house-trained as well as crate-trained. He 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. Twix will do best with experienced, active dog owner(s) who are able to be consistent with good daily habits to strengthen his foundational training. He walks very well on leash and knows how to heel. Twix prefers to be the only pet in the house. Small children are not recommended due to size and energy level. He is neutered, in great health and UTD on all vax. Please consider giving this deserving boy a second chance at a forever home. He is waiting for you and he’s sure to win your heart.

Story

Sweet, soulful, and secretly a snuggle-bug, Hilly is a 4-year-old bullmastiff with the kindest eyes and a heart full of love just waiting to blossom. Though she may be shy at first and might give a little grumble when meeting someone new, don’t be fooled—Hilly warms up with gentle patience and quickly becomes your biggest fan. Once she trusts you, she’ll offer soft, sweet eye contact and soak up all the love you can give. Whether it`s quiet leash walks, or lounging about, Hilly is a calm and polite companion. She`s curious about toys (especially balls!) but still learning how to play. Hilly already knows `sit` and would thrive in a calm home with older kids (12+). If you’re looking for a loyal, loving dog who just needs a little time to shine, Hilly might be your perfect match. Her heart is big—she`s just waiting for the right person to help it bloom.

Story

Cookie Monster is slightly over 100 pounds. He is about six years old, he was surrendered by people who could no longer care for him. He’s very people friendly. He loves to sit on your feet. He likes to play ball. He likes to stretch out and have a belly rub head scratch although he is dog selective and likes some dogs. The Shelter feels he would be best to be placed in Home as the only dog, he would do well in a large apartment or house exercise but he is past the stage where he needs very strenuous exercise no children under 13
